AS SALAMO ALAIKUM BHAII

Please see attach both videos 0f drilling with 90degree angle head...its looking good only in kinematic machine simulation in pro-e environment..but when i make a g-code of this file and check on machine then there are totally different behavior of my machine i don't know wat happen, please guide me regarding it i have to drill with 90degree angle head.....PLEASE DON'T CONSIDER THE ROTARY ATTACHMENT BECAUSE I HAVE TO DO THIS WORK ON SIMPLE 3 AXIS MACHINE..

MACHINE I HAVE DAHLIH MCV270 WITH FANUC21iMB CONTROLLER
ALSO ATTACH THE CURRENTLY USE POST PROCESSOR FOR 3- AND 4+1 AXIS MACHINING

THANKS

.....but when i make a g-code of this file and check on machine then there are totally different behavior of my machine i don't know wat happen, please guide me regarding it i have to drill with 90degree angle head.....

Your problem may be the Z Tool Length Offset being applied.

Hi fsa:
To begin with, when you use an angle attachment, must modify your postprocesor; because yor axis are turned around.
By looking at your code and the posted videos I asume the working position. (I might mistake some dimension, sorry about that.)
You must position the machine ( in between lines 30 and 31) in "X 192.360" ( first hole) and "Z -159.300", then apply Tool Length Offset N 31 G0 G43 Y 11 H3 M8 ( NOW this is your drilling axis) and will put the tip of drill at 11 mm from the front of part. I asume that Y0 is in the front of part. I would have setted so.
N 33 G83 Z-008.600 Q.5 R13.4 F80 ( drilling to a depth of 8.6 mm.)
N 34 X 173.360 ( second hole; you're moving sideways)
N 37 G91 G28 Y0 ( for safety, first clear the driling axis out of the way)
N38 G91G28X0.Z0 ( now move the Z axis to the home.
Remember I just analized your Gcode and came to this conclusion; need more help? just ask.

I suggest coordinate rotation is needed:
G19 (YZ Plane)
G68 Y-192.36 Z0 R-90 (Centre of Rotation.)

Code as if on the XY Plane and apply Tool Offset to Y Axis.

yaar may aap say milsakta hon kia may nay apni machine pay chali hai >>mujhay option milgya hai pro/e may >right angle haed pay kaisy kaam kartat hai>>>>

[faiz ahamd]

aap ki jo post bani hai wo 4 axis k hisab say bani hai >>is liay ye run nahi hogi >>>

hello kiwi ???? cant undrstand ur post

hello kiwi ???? cant undrstand ur post

Suggest you goggle G68, there will be examples better than I can explain.

EDIT
I think your code needs to be like this.
