• Referenced GMC Operation


Capabilities• Enhancing GMC in such a way that the user can

more easily describe a motion sequence andreapply it from a template without going into eachsub-operation for redefining input

• Framework for providing better OOTB coverage forcycle based probing

• Not limited to probing, can also be used for othermotion sequences like complex hole machining orspecialized milling that our current processors donot support

Customer Benefit• Create controller and company specific user-cycles

for specialized machining methods

Referenced GMC Framework


• A Reference sup-operation has beenadded to define key input

• When applied from a template the useronly has to satisfy the key input in orderto get the motion sequence executed

Front End for Key Input & References (Apply from Template)


• The motion sequences are described byusing regular sub-operations that havebeen extended. The sub-operations nowallow input to come from the operationlevel

Front End for Key Input & References (Motion Authoring)


• Allows to define a set of key input parameterssuch as points, vectors, coordinate systems,doubles, etc. that can be put on the maindialog

Front End for Key Input & References (Authoring)


• GMC is the first operation type that allows theusage of expressions in move definitions, loops& conditionals

• For every input defined, the system creates anexpression that can be used when constructingthe motion sequence

• Every input field of a sub-operation nowprovides and option to describe a functioninstead of a fixed value

Expressions


• If a tool is defined for a Referenced GMC operation, forevery tool parameter the system automatically createsexpressions that can also be used when constructingformulas

Expressions


• A Conditional Move sub-operation has beenadded to execute a set of sub-operationsbased on conditions

• Conditionals can be used in combination withloops

Loops & Conditionals


• A Loop move sub-operation has beenadded to allow repeating set of sub-operations multiple times

• Provides input on how many times the loopis executed and a loop counter that can beused in embedded sub-operations

• Loops can be nested and used incombination with conditionals

Loops & Conditionals

• Turning


Customer Benefits• Support for modern mill turn machine centers which offer

the capability to combine profile turning with continuoustool axis orientation.

• Increased tool life and improved surface quality as theinsert cutting angle can be kept within an optimal range inrelation to the surface.

• Reduction of setup and operation times as complexcontours which would require several operations with fixedtool axis orientation can be created in one operation.

• Reduction of the number of tools as operations whichwould require several tools with fixed orientations can becreated with a single operation using a single tool.

• Ability to cut into areas which are difficult to reach withfixed axis configurations.

curve)


Multi-Tool

Capabilities• Define spindle orientation angle (Index Notch) and tracking

point(s) per tool component (cutter)• Retrieve Multi-Tool from (ASCII) tool library or MRL

(Teamcenter)• Parametric representation per tool component• 3D Solid representation for the entire Multi-Tool• Sim15 example will be using Multi-Tools• See Whats New Videos

Customer Benefits• Create your own multi-tool object from the 3D-CAD model• Export your own multi-tool to the tool library• Editing a multi-tool and its cutters in the ASCII library is no

longer needed• Defining the multi-tool kinematics using the Machine Tool

Builder application is non-essential

• Kinematics based Transition Path


Capabilities• Is providing machine kinematics based

transition path between two operations that areusing the same tool

• Is considering the kinematic capabilities andrestrictions that are defined with the machine

• Is providing a single repository (template) permachine for configuring and storing transitioninstructions/rules

• Is using dedicated GMC motions to describe:• Start/End of Program locations• Tool change position and how to get there• How to get to cutting positions after tool change• How to transition between operations (move to

machine positions, order of axis, simultaneouslyor individually)

Kinematics based Transition Path (preview)

NX12.0.2 Prev.


Customer Benefits• Program in machine context and utilize the

transition path trace to catch possible transitionproblems during programming

• Helps organizing operations into sequences thatprovide more efficient transitions paths

• Conveys all necessary data to the post so that thepost does not have its own instructions/rulesanymore and can be kept more generic

Kinematics based Transition Path

NX12.0.2 Prev.


Each machine can have its own template that describesthe “safe” transition path motions rules per GMC:

• Before the first operation• Between operations• After the last operation

The template (interop.prt) is located in the graphics folderof the installed machine


..\mach\resource\library\machine\installed_machines\sim08_mill_5ax\graphics\interop.prt

NX12.0.2 Prev.


Example: 3 motions described for rule in between operations

Move in Z to the Machine LimitMove AMove C(Move to the next cutting position)


NX12.0.2 Prev.


Example: 2 motions described for rule in between operations

Move 100 mm in Z+Move A and C simultaneously(Move to the next cutting position)


NX12.0.2 Prev.


Example: 1 motion described for rule in between operations

Move 100 mm in Z+(Move to the next cutting position)à shortest path
