Cutter Comp. issue

[Anonymous]

Hi guys.

I am not getting the right cutter compensation output in my post processor.

In the sample attached, I have made a simple contour and set "cutter comp" to "wear".

I am using the latest Generic Heidenhain post processor from Autodesk's posts.

In the Heidenhain language "Cutter comp" is defined by either "RL" or "RR". In my case I need it to be "RL" (Radius Compensation Left) as I am "Climb Milling".

The post processor is only picking up on the first linear move of the contour with "RL" turned on.

what I need is "RL" to be in every single block until "cutter comp" again is canceled with "R0" in the last line of the contour. 

By editing the Post Procesoor, how do I change this?

Hope someone is able to help me here. thanks!

Sample File and Post Processor attached...

Here's how the code looks at the moment (Fusion 360 - Generic Heidenhain Post Processor):

25 L X-41.8 Y+32.8 Z-22 RL F214
26 CC X-40 Y+32.8
27 CP IPA+90 DR+
28 L X+40 Y+31 F300
29 CC X+40 Y+15
30 CP IPA-90 DR-
31 L X+56 Y-15
32 CC X+40 Y-15
33 CP IPA-90 DR-
34 L X-40 Y-31
35 CC X-40 Y-15
36 CP IPA-90 DR-
37 L X-56 Y+15
38 CC X-40 Y+15
39 CP IPA-90 DR-
40 CC X-40 Y+32.8
41 CP IPA+90 DR+ F214
42 L X-38.8 Y+34 R0

And here's what I need the code to look like: (From Different CAM package - Heidenhain Post Processor).

12 L X+50,142 Y+0,488 RL F214
13 CC X+59,3 Y-1,131
14 C X+50,0 Y-1,131 DR+ RL 
15 L Y-15,0 RL 
16 CC X+40,0 Y-15,0
17 C X+40,0 Y-25,0 DR- RL 
18 L X-40,0 RL 
19 CC X-40,0 Y-15,0
20 C X-50,0 Y-15,0 DR- RL 
21 L Y+15,0 RL 
22 CC X-40,0 Y+15,0
23 C X-40,0 Y+25,0 DR- RL 
24 L X+40,0 RL 
25 CC X+40,0 Y+15,0
26 C X+50,0 Y+15,0 DR- RL 
27 L Y-4,131 RL 
28 CC X+59,3 Y-4,131
29 C X+50,142 Y-5,75 DR+ RL 
30 L X+56,2 Y-5,263 R0

What model of Heidenhain control do you have? Once RL is active it will be active for all the subsequent lines, until it gets a R0.

Have you tried to run it?  That code should work on any Heidenhain from a TNC 155 and up to the current models.

Thank you Mike. You were absolutely right.

Glad to help. I have a soft spot in my heart for Heidenhains. Super powerful control with an excellent macro language.
