Control Plunge rate & Retract rate
« on: January 14, 2009, 04:16:48 PM »
Hello!
When I design a drill patern in my Cam program the G code that generate is with a general Feed-rate.
In program the  Plunge rate & Retract rate fields are inactive.
also it does not include the tool feed-rate preferences.
the code  that generates is something like that:

Any idea how to control the Plunge rate & Retract rate? ??? ??? ???
Lets say
Plunge rate 200
Retract rate 600



(PROGRAM NAME - 5X5 holes 2mm per 10mm )
(DATE=DD-MM-YY -  14-01-09  TIME=HH:MM -  23:05 )
N100 G17 G21 G90 G40 G80 G64 G49 G0 M05
N102 G8 P1
N104 G90 M05 Z0
N106 G52 X0. Y0. Z0.
N108 T12 M06
(  2. DRILL )
( TOOL - 12  DIA. OFF. - 0  LEN. - 0  DIA. - 2. )
N110 G54 G0 X-105.183 Y-23.882
N112 S0 M3
N114 G43 H0 Z60.
N116 Z5.
N118 G17 G99 G82 Z-6. R5. P300. F4000.

GEORGE,
How about trying one of the wizards available in MACH and just compare the Gcode.
Good learning and may be interesting.
Lazy answer on my part but will be more fun for you,

HIYA George , The the plunge rate is set by your cam program. Probably under the tool setup section . THe retract rate is controlled by MACH when using a canned drill cycle and is not normally changeable. THe option to this is to program the actutal drill cycle as a sub program then you can have independat plunge and retract feeds.

Hope that helps, (;-) TP
