BASIC CONCEPTS

Machine axes X-, Z- and B-axis and their respective positive and negative displacement directions are shown on the above schematic diagram. Y+ and Y- axis are not shown Y- is towards machine bed and Y+ away from the machine bed, 50mm+,50mm– to give stroke of 100mm. (machine needs to be on Y zero for turning operations). As you can see, when workpiece zero reference point is located on workpiece end (most common case), the positive direction is outside the workpiece, while the negative direction is on the workpiece area to be machined (inside the workpiece). Commonly, you will operate in the quadrant defined by X+ and Z-. The machine will enter only in X- area for facing operations. C-axis would be used to swivel the main spindle head in order to position the work piece for drilling operations using a powered tool. C+ is in clockwise direction and C- is counter clockwise direction.

Other axes that could be encountered when programming the machine are

F: feed axis (related to slides) to be programmed when in operation. In millimetres x per revolution when the head is rotating (turning) For example: G99 F0.3 this means “03 millimetres per revolution”. In millimetres per minute when the head is stopped (MC). For example: G98 F80 this means “80 millimetres per minute” T: is turret rotation. R: is radius programming. S: are head revolutions (cutting speed) This letter is always related to heads. G50 S1000 Rpm limit. G97 S1000 fixed rpm (for tapping and drilling). G96 S200 cutting speed (m/min) for all turning operations.

Cutting speed formula:

Vc= Cutting speed D= Part standard diameter n= Rpm limit.

,C: Chamfer programming. ,A: Angle programming.

Machines must be at the X home position for turret indexing.

Vc×1000

π×D n=


Tool offset The required offset values must be entered each time tool position is changed with respect to the aforementioned position; if tool position is not changed, entering a offset value will not be necessary as these values are stored in the memory.

Entering tool offset values There are two ways for entering tool correction values. 1st.) Supplied with presetter. For machines with presetter, place the presetter in position and preset the tool. 2nd.) supplied without presetter. For machines without presetter, turn the work piece and retract the tool without moving it out the axis. Then measure the work piece and enter the readings in the geometry table. To enter a value, go to the geometry table (offset value), enter the required value and press the intermediate key; by this way the control unit will calculate the offset value.

Workpiece zero reference point Workpiece zero is the distance that the workpiece protrudes from main chuck face.

We advise you to enter workpiece zero at the beginning of the program. X and Y can be omitted but for safety it should be included. G10 P0 X0. Y0. Z-80. “WORKSHIFT”

In this manual we will always refer to G codes type A. Comment:: These are notes included in the program. These notes are totally optional, and it is up to the programmer to enter them or not. These notes will be always placed in round brackets () in order to prevent the program reading them. T101 Here is shown that the tool to be used is in position 1 and a offset value of 01 is applied. T0101 could be also entered, as the four mandatory characters are present, however, the first zero is optional. Head rotation direction: M3 head rotation direction forward M4 head rotation direction reverse M5 spindle stop

If instructing the reverse from the forward direction or vice versa, the spindle must be stopped first. This is also valid for the sub spindle and live tools. G0 X150 Z100 Note that tool retraction in this example is to 150 mm on X+ and 100 mm on Z+ from work piece zero, and not from chuck face, as no order for changing the position is given to work piece zero, which in this example is maintained in the previous position. Line number (N10, N20...) Line numbers are optional, and can be either entered or not. G0 G40 G99 X45. Z0. M8 As you can see, G codes are first placed and then X, Z and M codes. Codes can be also entered in the following manner: G0 X45. Z0.G99 G40 M8 Entering codes such as G96 and G50 in the same line is not permitted.

G112 or G12.1 Polar coordinate interpolation Polar coordinate interpolation is used when it is desired to perform milling operations on the face of the work piece, which require synchronous movement of the spindle and live tooling mounted on the turret. When polar coordinate interpolation is commanded by the G112 or G12.1, the control interprets several pieces of data to determine the direction and speed at which the axes must be moved to reach the commanded end point. The drawing below shows the coordinate system used with polar coordinate interpolation. The programmed end points are laid out as coordinates on this plane. Note the signs for X and C. The following program examples illustrate the use of this system.

1. The following G codes may be used when G112 is active: G1, G2, G3, G40, G41, G42, G65, and G98.

2. G0 positioning is not allowed when G112 is active. 3. When using G2 or G3, the arc radius is specified using the R word. 4. M45 C axis mode must be active before commanding polar coordinate

interpolation. 5. The spindle should be oriented to C0 degrees before commanding polar

coordinate interpolation. 6. If machining in the X axis only, do not activate polar coordinate interpolation. 7. The unit of command for the C axis, when polar coordinate interpolation is used,

is MM or inches, not degrees. 8. When using cutter compensation during polar coordinate interpolation, the same

basic TNRC rules apply as with normal lathe programming. However, the following rules must also be observed:-


The tool radius and the quadrant must be loaded into the geometry offset file. For polar coordinate interpolation, the X tool offset represents the centre of the cutter and the tool tip location (Quadrant) will be set to 9.

9. The TNRC start up block (G41 or G42 line) must be programmed after the polar

coordinate interpolation command (G112 line) has been activated. For polar coordinate interpolation, the X axis move must be equal to at least two times the tool radius entered in the tool offset file. Program the G40 (TNRC cancel) command before the block containing the G113 or G13.1 (cancel polar coordinate interpolation).

10. Program restart and block restart are not allowed when G112 is active.

11. Specify the feedrate as millimetres per minute.

12. X values are diameters and C values are radii

|G107 or G7.1 Cylindrical Interpolation Cylindrical interpolation is used to perform contoured milling operations on the outside diameter of the workpiece. The Z and C words are used to specify the end points of the moves. When using cylindrical interpolation, the C word is programmed in degrees. C is also used to specify the radius of the part in the G107 or G7.1 block which activates cylindrical interpolation. The X word is used to program the depth of cut.

1. The following G codes may be used when G107 is active: G1, G2, G3, G40, G41, G42, G65, and G98.

2. G0 positioning is not allowed when G107 is active. 3. When using G2 or G3, the arc radius is specified using the R word. 4. M45 C axis mode must be active before commanding cylindrical interpolation. 5. The spindle should be oriented to C0 degrees before commanding cylindrical

interpolation. The formula for calculating the value of the C word is shown in the following program example.

6. If machining in the X axis only, do not activate cylindrical interpolation.

7. The H word is used to program incremental C axis moves.

8. Machine lock mode MAY NOT BE USED when G107 is active.


9. The unit of command for the C axis, when cylindrical interpolation is used, degrees, not MM or INCHES. 10. When using cutter compensation during cylindrical interpolation, the same basic TNRC rules apply as with normal lathe programming. However, the following rules must also be observed. The tool radius and the quadrant must be loaded into the geometry offset file. For cylindrical interpolation, the Z tool offset represents the centre of the cutter and the tool tip location (Quadrant) will be set to 9. 11. The TNRC start up block (G41 or G42 line) must be programmed after the cylindrical interpolation command (G107 line) has been activated. For cylindrical interpolation, the Z axis move must be equal to at least the tool radius entered in the tool offset file. Program the G40 (TNRC cancel) command before the block containing the G107 C0 (cancel cylindrical interpolation). 12. Program restart and block restart are not allowed when G107 is active. 13. Specify the feedrate as millimetres per minute.

Servo tailstock setup

The tailstock on the NL200Y is servo driven and is the “B” axis. It has the facility to be positioned and have the desired thrust set using a custom page on the control. Pressing the “CUSTOM” button on the control panel will bring up this page

The following parameters will need to be set #1 THRUST This sets the initial pressure that the tailstock applies. #2 THRUST This sets a secondary pressure if required ERROR This is a positional tolerance in microns for the “hold coord” DEC COORD This is the position where the tailstock will rapid too. HOLD COORD This is the position that the tailstock will feed to and apply the required thrust as previously set. BACK COORD This is the retraction position for the tailstock. These parameters will need to be set before using the tailstock. To operate the tailstock you will first need to set your thrust and positional parameters. Using the curser buttons cursor to the parameter to the parameter to change. The thrust parameters are set by using the soft keys at the bottom of the screen F2 to F5. By pressing these buttons you can dial in your required thrusts.


Servo tailstock initial setup

• To set the tailstock position initially bring the tailstock up to the job using the hand wheel until it is a safe distance away from the part then press “DEC COORD”

• Now move the tailstock forward until the centre engages the part then press “HOLD

COORD”

• The “BACK COORD” can then be set to a retract position that will allow the finished part to be removed.

• To change the other figures you can either input them directly or use F1 Measure. Pressing

F1 Measure will input the position that the tailstock is currently in.

• Once these parameters are set you can then control the tailstock in the program. M62 will rapid the tailstock to the “DEC COORD” then it will feed to the “HOLD COORD” and apply the set pressure.

• M22 will set the #2 THRUST (optional)

• M63 will retract the tailstock to the “BACK COORD”


U Drill adaptor installation

The NL200Y is equipped with a servo tailstock and is the “B” axis. It has the facility to be used as a fully programmable driven axis enabling the use of U-drills. The machine is supplied with two tailstock adaptors one with a morse taper for use with a centre and one with a parallel shank to suit U-drills. The taper adaptor comes pre-fitted to the tailstock. The following instructions are how to fit the adaptor for the U-drill. Using manual jog or the hand wheel bring the tailstock forward to enable full access to both ends of the tailstock.

1. Using a 6mm allen key loosen and remove the M8 cap head screws holding the morse taper adaptor to the tailstock body. Using two longer M8 bolts insert them into the two threaded ejector holes on the front of the adaptor plate. Gradually tighten these two screws until the front of the adaptor separates from the tailstock body. Once this is done you can then remove the adaptor by pulling the adaptor forwards out of the tailstock body.

2. Now you will need to remove the rear part of the morse taper adaptor. Using a suitable

spanner undo the coolant delivery pipe. Then using an allen key remove the three cap head screws that secure the rear adaptor plate. You can now remove the rear adaptor plate by pulling it out gently parallel to the body housing. Now that these two parts have been removed put them in a safe place for when they are required again.


3. The U-drill adaptor consists of three parts, The U-drill holder that goes into the front of the tailstock,

the rear coolant pipe support plate and the coolant pipe. Apply a small amount of grease to the U-drill holder and then insert it into the front of the tailstock body. This needs to be done gently as the diameters are a precision fit. Do not use a hammer to fit this part! When it is in all the way, index the adaptor until the two flats are aligned with the two flats on the tailstock body. Insert cap screws and tighten. This is the front part complete.

4. The rear plate screws on to the back of the tailstock body using three cap screws.

5. The coolant pipe inserts through the rear coolant pipe support plate. This is then screwed into the back of the U-drill to provide through tool coolant. The adjuster nut is then tightened up to the coolant pipe support plate.


6. To connect the coolant delivery pipe drive the tailstock all of the way back to home then remove the rear door to allow access to the pipefitting.

7. The coolant delivery pipe can then be connected to the coolant pipe and tightened with a suitable spanner. The installation of the U-drill holder is now complete. To change back to the morse taper holder is a reversal of these instructions.
