FOREWORD

The Society of Manufacturing Engineers, founded in 1932, is one of the largest

professional societies for education, research and development of industrialmanufacturing. The Taipei Chapter (No.242) established in 1972, has been instrumental

in sponsorship of numerous activities for promotion of manufacturing technologies both

in Taiwan and the international arena. Thus, the 2005 and 2007 SME International

Conference on Advanced Manufacture was successfully held in Taipei and Tainan.

The booming economic development in Asia, particularly the leading manufacturing

industries such as semiconductors, liquid crystal display, computer, cellar phones,commercial electronics and micro/nano areas have been attracting intense attention

among universities and research development-based institutions as well as many

industrial corporations. The knowledge-based industries have been enjoying immense

growth potentials; thus, there is an urgent need of a strong focus for exchange of various

scientific, technical and management aspects across the wide spectrum of the society.

We are happy to host the 2010 International Conference on Advanced Manufacture.

ICAM 2010 will include plenary speeches and technical sessions. The topics will cover a

wide range of manufacturing and instrumentation technologies.

The conference is also financially supported by the National Science Council and

Ministry of Education. The strong backup from these organizations provides an important

assurance for the success of ICAM 2010.

Welcome to ICAM 2010!

Best regards,

Professor Shih-Chieh Lin, D. I. Shaw

ABSTRACT - Recently, research on new techniques of single-chamber mufflersequipped with a perforated tube has been addressed. However, research work on shapeoptimization of multi-chamber silencers hybridized with perforated plug/non-plug tubes

along with work on the maximal allowable back pressure of mufflers has been neglected.Therefore, this paper will not only analyse the sound transmission loss (STL) of aspace-constrained two-chamber muffler hybridized with perforated plug/non-plug tubes(Figure 1) but also optimize the best design shape under a specified pressure drop.

In this paper, both the numerical decoupling technique and simulated annealing (SA)for solving the coupled acoustical problem of perforated plug/non-plug tubes andoptimizing the muffler shape are used. To verify the liability of SA optimization, optimalnoise abatements for the pure tone (500 Hz) is exemplified and shown in Figure 2.Results indicate that the maximal STL is precisely located at the desired target tones.

Consequently, as indicated in Figure 3, the optimal result of one case study foreliminating broadband noise also revealed the overall noise reductions with respect to themuffler at various maximal allowable pressure drops ( maxp ).

ABSTRACT - This paper presents studies for ABS RP pattern used directly ininvestment casting, experimentally and theoretically. Ceramic mould shell preparationprocedures including CAD pattern designing; RP pattern formation; pattern surface finishand sealing; de-waxing and burnout are discussed.

Effects of pattern geometries such as bulk solid and thin wall are studied. The Resultssuggest that for the process to be successful, the preparation should start as early as CADdesign stage. For bulk solid geometry patterns, Shell function in CAD and Sparseweb options in RP pre-processing are proved very effective and should be applied incombination. While for patterns with thin-wall, Hot-Water De-Wax before plastic burnoutproved to be successful (Fig.1).

The mechanism behind has been revealed by our transient, non-linear CAE analysis.The comparison of the thermal stresses in the ceramic shell during the heating processesis plotted in Fig.2. It is very obvious that burnout process (although with higher oven

temperature) creates far less thermal stresses than the de-wax process (although withlower oven temperature).Therefore in any case, the Hot-Water De-Waxing procedure before plastic pattern

burnout was proved to be a good option to reduce the possibility of ceramic shell crack.

ABSTRACT - Chevron cracks or central bursts are encountered in a cold extrusion ordrawing process. While chevron crack causes fracture of the material during the process,internal cracks might exist resulting in fracture as well. Such internal cracks are difficultto detect and easy to cause severe problems in the manufacturing products. Thus,

prediction of chevron cracking will be an important issue in the process control. In thepresent investigation, a numerical algorithm based on the element deletion method andrigid-viscoplastic finite element approach based on Cockcroft-Latham and specific plasticwork fracture criteria was applied to predict formation and evolution of possible crackingin a cold extrusion of aluminum and steel alloys. Cockcroft-Latham fracture criterioninduced an internal crack while an external crack occurred owing to the specific plasticwork criterion in simulations. As a result, Cockcroft-Latham criterion was found to bevalid for predicting chevron cracking in comparison with the experimental observationavailable in the literature. Using Cockcroft-Latham criterion, cracking was carefully

investigated in terms of the size of the crack and gap distance between cracks dependingon the number of elements and boundary condition at the punch interface. The criticaldamage values for the Cockcroft-Latham fracture criterion were also calculated based onthe tensile instability and fracture conditions to investigate their effect on possiblecracking. Finally, processing map based on the Cockcroft-Latham fracture criterion forpreventing chevron cracking in the cold extrusion of commercially available steel wasdeveloped by considering processing parameters such as reduction in area and semiconeangle. According to this investigation, the developed element deletion method with theCockcroft-Latham fracture criterion was reasonably accurate for carrying out chevron

cracking analyses in the cold extrusion with proper selection of a critical damage value.

ABSTRACT- This paper presents a general approach for planning trajectories for cyclicdynamic systems, and demonstrates its application for robotic yoyo playing. Theapproach is based on return map parameterization using intermediate states of the system.These states are naturally incorporated as the boundary constraints in the framework of

nonlinear optimal programming. In the case of yo-yo playing, the height of the robot armwhen the yoyo arrives at the bottom is selected as the intermediate state. By solving theoptimization problems during each phase of a cycle, a reference trajectory, a nominalcontrol for the robot and the corresponding return map of the object were generatedsimultaneously. The return map is naturally parameterized by the intermediate state. Thereturn map can be regarded as discrete-time system and the intermediate state can beregarded as a virtual control. Hence, standard analysis and design methods for purediscrete-time systems can be applied to control the dynamic system.

P-021 A simple Iterative Method for Minimum Zone Sphericity

Error Evaluation

Changcai Cui, Wei Fan

College of Mechanical Engineering and Automation, Huaqiao University,Quanzhou 362021, China

E-mail:[email protected]

ABSTRACT In order to evaluate the sphericity error of spherical parts precisely andconveniently, a minimum zone method is proposed which is realized by iterativelysearching the neighbourhood of an approximate optimal solution. The neighbourhood is aspherical search space. The method starts with determining the initial centre and radius ofthe search space by an approximate method. The search space is divided by a series ofconcentric spheres. Then for every sphere it is further divided by some longitudes andlatitudes, the intersections of which are the candidate search datum centres of twoconcentric spheres for the sphericity error evaluation as shown in figure 2.

A better candidate centre with minimum sphericity error will be found and reservedas the new location of the search space and a new radius of the search space will becalculated according to the location transformed distance from its former location. Thenew search space is therefore divided as above and a new better candidate centre will befound. The computation continues until the favorable solution appears. Results of some

examples show that the proposed method is precise and relatively efficient for generalinspection as shown in figure 4 besides it is simple and easy to realize.

P-024 Nano-Fabrication Using Design of Square-Shape Tool on

PET Surface of Digital-Paper Display

P.S. Pa

[email protected]

ABSTRACT The low yield of ITO nanostructured coatings is an important factor inoptoelectronic semiconductor production. This study demonstrates a designedsquare-form tool and a precise reclamation system using a micro electroremoval processfor ITO thin-films dissolved from a surface of PET surface of touch-panel. In the currentexperiment, a small gap-width between the square-form tools cathode and the anodeworkpiece, takes less time to do the same amount of ITO dissolution. A large diameter ofthe rotational circle of the cathode of the square-form tool reduced the amount of time foreffective ITO removal since the effect of dissolution is facilitated by supplying sufficientelectrochemical power. A higher dissolution rate of the defective ITO thin-filmscorresponds to high rotational speed of the rectangle-form tool, a high temperature, or alarge flow rate of the electrolyte. A small chimb end radius of the anode combined withenough electric power, results in fast dissolution. Additionally, electric power, whencombined with a fast feed rate, provides highly effective dissolution. Importantly, theperformance of a designed rectangle-form tool was found to be more effective in the

micro electroremoval process. It requires only a short period of time to dissolve the ITOsnanostructured coatings easily and cleanly. By establishing a designed tool and a precisereclamation process for the ultra-precise removal of the thin nanostructured coatings, theoptoelectronic semiconductor industry can effectively recycle defective products,reducing both production costs and pollution.

ABSTRACT - In general, the electromagnetic forming process mostly relies on the useof the electromagnetic force to deform metallic workpieces at high speed. The force isinduced by the high current and voltage with a coil set. This, however, would result thehigh design cost and the temperature rising problem. In this study, a micro-formingprocess is designed that the induced electromagnetic force will attract the ferromagnetic

punch to contact the workpiece, and then forced the workpiece to deform. Theexperimental apparatus for the electromagnetic micro-forming process is designed andtested.

ABSTRACT - Size effects make traditional macro-forming generally ineffective forunsuitable micro-forming. Although the micro-tube is one of the most importantmicro-parts, the effect of size on material behavior has seldom been studied. In thisinvestigation, 304 stainless micro-tubes were annealed to investigate their grain growth asshown in Figure 1 and to analyze the mechanical properties, including yielding stress andstrain-hardening coefficient, by conducting a tensile test. The thin oxidation layerprecipitated although the thermal treatment was performed in a vacuum environment. ATriboindenter system was employed to measure the reduced modulus and hardness of theoxidation layer and grain to identify the effect of the oxidation layer on mechanical

properties. A flaring system was developed to investigate the relationship between flaringlimit and T/D (thickness/average grain size) ratio as shown in Figure 2. The method offabricating a conical micro-punch was also described. Consequently, the optimal T/Dratio, which enhances the flaring limit, is 8.9 as shown in Figure 3.KEYWORDS- flaring limit. grain size effect.

ABSTRACT- Traditional tissue engineering scaffold fabrication techniques usually havelimited control of the micro-architecture of the scaffold with random pore orientation,resulting in variations in mechanical properties. Solid Freeform Fabrication (SFF)techniques, building parts layer by layer without restrictions on shape andmicro-architecture control and consistency, provide a great opportunity to fabricate 3Dscaffolds. In this research, a self-developed Dynamic Masking Rapid Prototyping Systemwas adopted to fabricate biodegradable PCL-PEG-PCL tissue engineering scaffolds. Thesystem utilized Digital Light Processing (DLP) projector directly as the dynamic maskwith modified lens setting. The PCL-PEG-PCL was mixed with PEG-HEMA, serving asbinder, and photo-initiator in acetone. Two types of scaffold pore patterns were designedand fabricated. Due to the reflection of previous cured layers, over-cuing happened andpores may be closed when the number of layers increased. Three strategies were appliedto solve this problemdecrease the exposure time of latter layers, reduce the scaffold

dimensions of latter layers for compensation, and assemble basic scaffold sets with fewerlayers. As a result, the assembling strategy was the best among the three. In the future,more 3D scaffold designs can be implemented through this system.KEYWORDS- Rapid Prototyping, Dynamic Mask, Tissue Engineering, scaffold,

ABSTRACT - This paper presents the synthesis of titanium oxide nanooils withsuspension stability using a modified plasma arc system. The high temperature was usedproduced by plasma arc system to cause the bulk metal to heat and vaporize. The titaniumoxide gas is induced into the collection piping by the induction system. Then it mixesthoroughly with the pre-condensed paraffin oil, and mixture with a rapid cooling processwhich helps in grain nucleation and prevents the growth of particle size. Hence, thenanooils with smaller spherical titanium oxide size can be obtained, and this is finallystored in collection tank. The friction test was analyzed using an ATE-77 ReciprocalTribological Tester made by Cameron-Plint Tribology Limited, England. Moreover, theviscosities of nanooils were measured with the DV+LVDV-UCP rheometer inrate-sweep mode over the shear-rate range 200-1900. The results show that the nanooilsmixed spherical titanium oxide can be made by modified plasma arc system. Theviscosity of nanooil consistently exceeds that the paraffin oil enlarging the partial EHLarea with a complete lubricating film between two move iron surfaces. It provides goodperformance, then warranting the use of the titanium oxide nanooils as revolutionarylubrication agent.

ABSTRACTThe design of the heat sink of a CPU depends on the material flow boardand length of the main model's bearing. Two plastic deformations were produced bydirect extrusion for achieving better billet flow. We mainly used DEFORMTM 3Dsoftware to simulate the plastic deformation behavior of billets during hot extrusion at aconstant temperature of the radial-finned heat sink. We then conducted a series ofsimulation analyses with different variables such as friction factor, ram velocity, and fingate stage of the die to evaluate the methods of decreasing the warping in the extrusionprocess. We used the Taguchi method to find the optimum design parameters. We alsodeveloped an experimental mold for CPU extrusion. The results confirm the suitability ofour design process of an extrusion die to achieve a lower warping behavior of theradial-finned heat sink. Figure 1 compares the simulation and the finished experimentalproduct, and a good result was obtained.

ABSTRACTSurface residual stress is unavoidable for components after manufacturingor polishing process. It could be either detrimental or beneficial to the service life of thecomponents depending on the conditions of the existing residual stress. The goal of this

study was to determine the surface and subsurface residual stress for metal thin films afterChemical Mechanical Polishing (CMP). Tungsten (W) thin films with thickness 600 nmon silicon wafer were chemical-mechanical polished at designed parameters withdifferent down pressures and relative velocities to generate the residual stresses onsurface and below surface. The stress measurements of the thin films were performed byGrazing Incident X-Ray Diffraction (GIXRD). The experimental results evidently showedthat the surface residual stresses were induced by the CMP processes. A high surfaceresidual stress was obtained, and the residual stress decreases rapidly along the depth forthe films polished by CMP.

ABSTRACTA method for predicting dynamic stability limit of thin-walled workpiecehigh-speed milling process is described. The proposed approach takes into account the

variations of dynamic characteristics of workpiece with the tool position (or machiningtime). A dedicated thin-walled workpiece representative of a typical industrial applicationis designed and modeled by finite element method (FEM). The curvilinear equation ofmodal characteristics (natural frequency, stiffness, etc) changing with tool position isregressed. A specific dynamic stability lobe diagram (DSLD) is then elaborated byscanning the dynamic properties of workpiece along the machined direction throughoutthe machining process. The results show that, during thin-walled workpiece millingprocess, material removing plays an important part on the change of dynamiccharacteristics of system, and the stability limit curves are dynamic curves withtime-variable. In practical machining, some suggestion is interpreted in order to avoid thevibrations. Then investigations are compared and verified by high speed millingexperiments with thin-walled worpiece..

ABSTRACT Insert injection molding is a process in which plastic is injected into amold that contains a pre-placed insert. During the insert injection molding process, theinsert can be deformed by the pressure of polymer melts. The deformation of the insertchanges the wall thickness of the injection molded part, which can cause several defectssuch as short shots or warpages of the parts. In order to reduce the deformation of the

insert, it is important to achieve successful design of gating system, insert geometry, andmolding conditions. In the present study, the insert deformation of the BLDC motor statorwas investigated by three-dimensional injection molding analysis using Moldflow. Theeffects of gate locations and insert geometries on the insert deformations wereinvestigated. Finally, the numerical results were compared to the experimental results.

ABSTRACT Compensation cutting is the final process for precisely machining anaspheric surface in ultraprecision machining work. In this paper, the effects to the formerror of a micro aspheric surface caused by the spindle speed and depth of cut wereexamined by factorial experiment with one control factor of compensation ratio beingfixed as 1. The experiment was performed for an oxygen-free copper (OFC) asphericmold with a diameter of 0.3 mm by using a 4-axis desktop ultraprecision machine,which has a feeding resolution of 0.1 m along each linear driving axis. According to theanalysis of variance (ANOVA) of the experimental results, the spindle speed is with alarger contribution of 56.04% compared to the depth of cut with 25.28% in affecting theform error of an aspheric surface. In addition, according to the characteristic curve, thehigher is the spindle speed, the smaller is the form error obtained. With the operationalconditions of the maximum spindle speed being 600 rpm and the depth of cut being thesame as the error caused by the rough cutting, i.e., 1.5 m, the most precise formaccuracy was obtained as 0.59 m among the configured experimental trials. Through this

study, how the control factors affect the form accuracy of a micro aspheric surface in thecompensation cutting process was demonstrated.

ABSTRACT It is identified that the electromagnetic electropolishing (EMEP) caneffectively prevent the electrolytic products from being attached to the tool electrode andthe curved surface and rapidly discharge dregs off the gap in the current study. In theexperiment, author uses a rotational plate shape tool electrode supplies with continuousand pulsed direct current to execute the EMEP. The experimental parameters are magneticstrength, distance between the two magnets, current density, on/off period of pulsedcurrent, initial gap width, flow rate of electrolyte, rotational speed of the tool electrode.For the design system, the higher current density with magnetic assistance can avoid thedifficulty of dreg discharge, thus reducing the finishing time. Small distance between thetwo magnets or large magnetic field intensity provides larger magnetic force anddischarge ability and better finishing. Higher rotational speed of the tool electrodeproduces better polishing. Pulsed direct current can slightly promote the effect ofelectrochemical finishing, but the electric current needs to be increased in proportion tocompensate the off-time. The EMEP without pulsed current is recommended for thepolishing process. It is a great contribution that the EMEP just needs quite short to make

the surface of workpiece smooth and bright.

ABSTRACT -With increasing delicacy in product shape and structure,manufacturing technology faces stricter requirements, especially for small anddeep internal thread processing. To reduce aircraft weight and increase flightspeed, the aviation industry uses a great deal of titanium alloy materials, withexcellent mechanical properties, on aircraft parts. Tapping is the most common

processing method for internal threads. However, small taps (smaller than M6)are prone to breaking the internal thread in the hole of a titanium alloyworkpiece.In the past, researchers thought that the introduction of ultrasonic assisted vibrationin tapping processes could generate smaller tapping torque than non-ultrasonicassisted vibration process. However, since the ultrasonic vibrators temperatureincreases with processing time, the temperature of the workpiece may get too high.As a result, the ultrasonic vibrator may generate an unstable resonant frequency andamplitude, which can cause poor quality in the workpiece. This research usedultrasonic assisted vibration and LabVIEW software to develop anultrasonic-vibration assisted automatic Tracing frequency system. With thisorthogonal array experiment, ultrasonic-vibration assisted automatic Tracingfrequency system and the appropriate processing parameters (vibration amplitude,vibration frequency) were used to perform tapping on a titanium alloy workpiece.The effect of using this system on internal thread processing was investigated.

ABSTRACT- Micro/nano structures patterned on the thin film substrate and fabricatedby the R2R (Roll-to-Roll) nanoimprinting processes usually have a steep andlow-reflective surface, which is not to be easily measured by existing optical methods. In

this paper, a multi-wavelength confocal microscopy with combined focusing curveamong three colors (Red, Green and Blue) is introduced to measure micro structures. Acompact and portable chromatic confocal microscopic probe was developed byintegrating a white light source obtained by mixing the LED light sources and a coaxialconfocal optical configuration with a 3-chip CCD camera for individual light sensing, asshown in Fig. 1. A fitted depth response curve (DRC) between the profile depth and themulti-color focusing correlation was established and calibrated by an accurate laserinterferometer. From analysis of the measurement results, it was confirmed that astandard deviation of 30 nm on the height measurement can be achieved. This confocal

profilometer can effectively measure any micro structured thin film fabricated by the R2Rprocesses, shown in Fig. 2.

ABSTRACT- The leveling mechanism is widely used in the precise instrument. In termsof the theory of mechanisms, the leveling mechanism is a spatial parallel mechanism. Itsmotion is complicated and degree of freedom is not direct. Degree of freedom formechanisms is a basic problem of the theory of mechanisms, and also is a premise ofmechanism design. Based on analytical theory of degree of freedom for mechanisms, thepaper analyzes degree of freedom and motion characteristics of two conventional levelingmechanisms, and points out that supporting kinematic chains in the two levellingmechanisms are zero terminal constraint. In different condition of inputs, the two levelmechanisms have different condition of constraints, degree of freedom is also different. Innatural condition, the mechanism is under-constraint, and has 3 degrees of freedom. In thecondition of one input the mechanism is under certain condition of inputs, and has 4degrees of freedom. In the condition of three inputs the mechanism has six degrees offreedom. These problems make a negative impact on the performance and working of the

leveling mechanism, and point out that it is significant that designing a levelingmechanism completely basing functional needs and kinematic principles.

ABSTRACT - Fe-PDMS is a composite material that mixing iron powders inpolydimethylsiloxane (PDMS) to form a magnetically actuated microstructures. In thispaper we describe fabrication of Fe-PDMS microstructures. Fe-PDMS at differentweight ratio ranging from 50% to 83.3% are tested for its for processing capabilities, aswell as its actuation performance. Material properties and processing parameters havebeen examined, and to demonstrate materials usefulness we have designed, fabricated,and tested micro pumps that utilize an Fe-PDMS microchannel structures, as shown inFigure 1. The Fe-PDMS microchannel for peristaltic pump design is the better choicefor disposal biochip applications because of its simplicity and cost-effective infabrication. In this Fe-PDMS microchannel study, Fe-PDMS=75% by weight wasfound to be the optimal parameter based on the maximum flow rate within processingcapability constraints, as shown in Figure 2. The flow rate achieved is 92 l/min forthe current Fe-PDMS microchannel design with the channel width (Wc) 1500 m,

channel height (Dc) 150 m and channel membrane thickness (Tm) 80 m. Drivingfrequency at 2.0 Hz is suggested for the optimal operation condition. These findingswould be useful to the design and operation for Fe-PDMS microfluidic devices.
