How to create the temp datum - Postprocessor

How to create the temp datum - Postprocessor

Dear All,

I have created Multiaxis Turn/Mill post,in milling post for angle hole drilling cycle,it should create the temp reference datum.(At the starting point)


Thanks and Advance

RE: How to create the temp datum - Postprocessor

Do you mean a cycle plane change in nc?

I think the recommended route is thru a main coordinate system and a local coordinate system. Then the post processor is supposed to output the proper angles. You might need to output mom_mcs_goto instead of mom_pos for the x y and z.

Thanks for reply

I HAVE ATTCHED THE SAMPLE FILE

N10 (DRIILING HOLE)
N20 M05
N30T1005
N40 G361 B-45.0 D0
M302
M45
G28U00V00W00
G97S2000M13
T1006
G00C00
G68.1X8.0Y0.0Z1.0 I0.0 J1.0 K0.0 R45
G43 H5Z0.1
G00 X0.0 Y0.0
G83 Z-1.0 Q2500 R0.0 F0.020
C180

After coming to G68.1 x,y and z,Next it should make the postion as zero.

RE: How to create the temp datum - Postprocessor

Mazatrol stuff by the looks of it.  

I suppose you use vector programming instead of mcs programming. If you use vector programming one way of getting there is use the first hole as origin for the cs transformation then switch to incremental and at the end of the drilling cycle switch back to absolute. You will need to ascertain that no M90 or M91 is  outputted in the cycles. Requires a bit of tcl programming. Switching between absolute and incremental is a bit awkward in nx I suspect two programmers worked on the same project and used different variables.

You could use mcs programming too then you can use the ugs stuff with local and main. Personally I do not like that method i.e. too much effort too get it wrong. There is a way around it with some additional coding. My customer likes to be able to move fixture offsets.

I am working on an is&v post processor for an integrex-e 410H-S whats yours?

I am working on Moriseki Fanuc controller.

You have any example of similar things.

RE: How to create the temp datum - Postprocessor

I am afraid not this is my first real mill turn. Milling machines has been my main line of business so far.
