PP - T67 Okuma

1       General Information

The standard has four configuration pages to manage all options available : CNC Controller : contains the options about CNC. Turning : contains the options of the turning technology. Code Management : allows to specify some codes for NC output. File Management : give some options for the NC file output.

 2       CNC Controller page

2.1         CNC Controller - Program Name as comment

 3      Turning page

3.1          Turning – Output Stock for CNC Simulation

 No stock output for T67_Okuma standard post-processor.

3.2          Turning – Output Tool and Plane for all operations

3.3          Turning – Use Parameters for Feed

3.4       Turning – Position Constant Cutting Speed

3.5          Tool Option – Output Tool List

3.6          Origin Option – Output Origin List

No output for T67_Okuma standard 

3.7          Origin Option – Multi Origin Management

No change for the standard T67_Okuma. No multi-origin management on Okuma.

With B axis machine :

The origin offset is outputted with the tilted plane function G127 with the G code G174.

3.8          Coolant Option – Coolant Activation Position

The second and third option will give the same output for turning operation.

There will be a difference by milling operations using livetools.

4       Code management page

4.1          Code Management – Enable C Axis Code

If the field is empty, the default code is M110.

4.2          Code Management – Disable C Axis Code

If the field is empty, the default code is M109.

4.3          Code Management – Clamping Code

If the field is empty, the default code is M147.

4.4          Code Management – Unclamping Code

If the field is empty, the default code is M146.

4.5          Code Management – Use axial interpolation mode

If machine don’t have code to output axial interpolation,it can be done in decomposed.

No circular interpolation will be output don’t use tool offset

Option	Result
	Output axial operation with interpolation
	Output axial operation decomposed

4.6          Code Management – Enable Axial Interpo Code

4.7          Code Management – Disable Axial Interpo Code

4.8          Code Management – Use radial interpolation mode

If machine don’t have code option to use interpolation, it can be done in decomposed.

No circular interpolation will be output don’t use tool offset

Option	Result
	Output axial operation with interpolation
	Output axial operation decomposed

4.9          Code Management – Enable Radial Interpo Code

4.10       Code Management – Disable Radial Interpo Code

4.11       Primary axis option – Management of primary axis

5       File management page

5.1          File Management – One physical File per Channel

Option	File 1	File 2
	(FIRST CHANNEL PROGRAM) … … M30   (SECOND CHANNEL PROGRAMM) … … M30
	(FIRST CHANNEL PROGRAM) … … M30	(SECOND CHANNEL PROGRAMM) … … M30

5.2          File Management – Generate the channel even if empty

Option	Result
	If a channel is empty no output of the program
	If a channel is empty, the program will be output but empty (Just O1001 and M30 will be output)

5.3          Listing / Synchronized File – Generate the Listing File

You need to set the Synchro Number mini & maxi to output the listing

Option	Result
	Don’t generate the file to see the synchro between channels.
	Generate the file to see the synchro between channels.

The file with the name Listing.TXT will be temporarily generated and shown.

5.4          Listing / Synchronized File – Synchro Numbers (Mini / Maxi)

Define here the synchronization Numbers (for example 1 – 9000)

The post processor will search for the synchronizations numbers between these mini and maxi values to generate the Listing.TXT file.

6       Launch page

6.1          Name of the NC File

Define here the Name of the generated NC file.

The extension is defined in the MCF configuration.

6.2          Comment Output

6.3          Block Numbers

6.4          Code for Program End

  7 Specific informations

7.1          MTE movement from the machine origin

Because the points are given in the system of axis of the machine, if there is 2 turrets not at 180 degrees, you have to recompute the X value to output a correct value in the turret axis system.

On Okuma machine there is no using of program origin. We have to program with using machine variable to be able to program fixed point from the machine origin.

We have to cancel the tool offset too.

To program a Z position relative to the machine zero without tool offset, we have to program the following lines :

Z=[<Z position to reach> - VZOFZ – VZSHZ - VETFZ]

X=ABS[<X position to reach> - VZOFX – VZSHX- VETFX]

VZSHZ is the current shifting added to the active offset.

VETFZ is the current active tool offset in Z axis.
