Solidworks CAM CAMWorks Postprocessor

yes we tried using the P as text and that is what we did in the START_OF_TAPE. But then we could not make it modal. So if we want to make it switch between different settings for rapid and cut moves then it would appear in every line. Also tried putting it in the RAPID_DOWN / RAPID_UP moves but did not get a reliable behaviour.

Ah, i understand. Sadly i can't help in this case...

Thanks for the quick reply. if the tool diameter needs to be smaller than half of the pocket diameter this would make sense. However, I understand the G41/G42 documentation that the coordinates from a G40 to a G41 move need to be at least R+dR away from each other to allow for the tool radius to fit in between. This would mean theoretically I could cut a hole with any tool that is smaller than the hole diameter (this is also what I would expect).

Example (with the numbers from above):
- we want to cut a hole that has a diameter of 10 around the origin
- we use a tool with diameter of 6
- we start in the middle of the whole

From what I understand the G-Code should look something like this:

The leadin / leadout have the length of 5 so it should be possible to use them as leadin moves from G40 to G41 and vice versa.

What am I doing wrong?

(of course, with the code above I would get the bump as described in the documentation but I wanted to have a very simple example with no overlaps and such)

Yeah, ok, that is better math than i did 
With that straight approach it should work... You should try that as a leadin-move in CAM. In the code earlier  you had an arc entry move, it's possible that this fucked up the G41 move in that small hole? 

 

Hi everybody.

Thanks a lot for this renewed PP.
But can someboby tell me, why at the end of the Gcode the first tool will be loadet again?
I think this makes no sense.

Here a litte peace from the end of my code:


G01 Z-14. F2500.
G41 D05 X101.024 Y14.324
G03 X100.6 Y14.5 I-.424 J-.424
G01 X91. F2520.
G03 X88. Y11.5 I0 J-3.
G01 Y-11.5
G03 X91. Y-14.5 I3. J0
G01 X100.6
G03 X101.024 Y-14.324 I0 J.6
G40 G01 X103.23 Y-12.118
G00 Z3.
Z25.

if you have solidcam installed, this post works great for me for the lathe (I found it here somewhere on the forum) 

Weird... I checked old code from that PP and it didn't load a Tool at the end.

examplecode with multiple tools used:

the problem is your gcode here :

G41 D42 X.907 Y4.487 F225.

Your tool is 42mm diameter ?? i think no

Remove D42 from gcode
