Drill cycles problems

Hello,

we have problems to simulate our Mazak's with Drill cycles.
The control is taken from library maz640m.

1. The cycle G73 is not correct.

Here is GCode :
T166 T804 M06
G91 G28 Z0.
G28 X0. Y0.
G00 G17 X-82. Y-17.5 S3800 M03
G43 Z150. M9M51
G90 Z2.
G94
G99 G73 Z-19. R2. Q2. F600.
Y17.5
G80
Z150. M09
M05
G91 G28 Z0.
The tools is everytime retract to Z2. but on the machine it's incremental 2mm up and than 2mm down and so on.
This simulation is right for G83.

2. The cycle G84 (tapping):
T908 T166 M06
G91 G28 Z0.
G28 X0. Y0.
G00 G17 X-82. Y-17.5
G43 Z150. M9M51
G90 Z2.
G95
S477
G99 G84 Z-15.75 R2. F1.25
Y17.5
G80
Z150. M09
M05
G91 G28 Z0.
G28 X0. Y0.
Vericut gives me a warning that the spindle still is standing.
O.K. i have no M03 in the GCode, but our Mazak's are doing it right, like when they see G84 , turn on the spindle.

How can i modify my control in vericut that everything looks good ?

Thanks

Re: Drill cycles problems

Drill cycle definitions in the control have a new and old method.  It depends on which you are using.   Send in a submission to CGTech, they can help you with this.

Re: Drill cycles problems

We have the old drill cycle logic.

I've now switched G73 in the control from CyclesDeep to CyclesDrill.
The tapping problem is solved by modify the cam-post to output M03.

Now i get no errors from Vericut and it looks good.

Thanks
