Need Help!- G83 - setting a speed of returning from the hole?

[mira.uherec]

Hello, can anybody advice me please, how can I change a rapid speed of returning the drill from the hole in cycle G83? When the drill is returning from the last peck to the R position, the speed is so fast that machine is pretty much "shaking". And does anybody know which parameter sets this limit of speed for the each one of axes.


Machine - Doosan Puma TT1800SY, Fanuc 16i TB,
Thank You for answering

the controller has a rapid over ride right ? if so turn it down . I would look of any know-en problems like the z adapter between the servo and screw getting loose (like a fadel) other then that the machine should be made to run like that .

Specify a lower rapid traverse rate. On 0i it is parameter 1420.

Program it long hand, no G83

it can also be used as a sub, for multiple holes

ie

G1 Z-20. F100.
Z3.
Z-19.5
Z-30. F100
Z3. F2000
Z-29.5
Z-40. F100.
Z3. F2000.
G0 Z50.

Thanks to everybody for help, I checked that #1420 and compared value to the machine catalog data and find out there were set a maximum (40m/min). Mira
