Hello. I have a problem in my SolidCAM 2014 with how it writes the G84 gcode.
The G84 tapping cycle of the Elexa control of my 3 axis milling machine needs to be written in such a way that;
S is the spindle speed
and F feed is the tap pitch in microns.
The control then calculates the real feed itself.

In the SolidCAM Tool library editor I can write the tap pitch and speed of the spindle, but the feed is calculated and can't be entered manually.
So for example if I set the tool spindle speed to 300 and the pitch is 1,25mm, the feed is calculated to 375

So the gcode generated is;
S300
G84 ... ... ..... F375
..
G80

But the correct one should be;

S300
G84 ... ... ..... F1250
..
G80

Now I have to manually edit the gcode in order to make it work properly. So far no taps broken...

So I wonder if there is any possibility to modify:
1) the way the SolidCAM tool library editor calculates the feed
2) modify the PP that instead of the 'feed' parameter writes the 'pitch' parameter (unavailable)

Any hints?
Thank you.

Easiest way is to edit pp and add equation for feed value (its f/s*1000) it should work anyway.
Values for f, and s are variables that u can easy find in gpp file.
As for using pitch directly- U would need to find that variable in Vmid, and i'm not sure if there is any actually, cause pitch of the taper is probably not used in gcode generating.

Hi, thanks for the reply.
It does indeed solve the issue!

Thanks a lot.
