9.2 G68. X axis roughing canned cycle
This cycle machines the programmed profile maintaining the indicated step between consecutive
machining passes. Triangular, round and square tools may be used in this cycle.
The basic structure of the block is as follows:
G68 X Z C D L M K F H S E Q
X±5.5
It sets the X coordinate of the profile's starting point. It must be programmed in absolute coordinates
and in the active units, radius or diameter.
Z±5.5
It sets the Z coordinate of the profile's starting point. It must be programmed in absolute coordinates.
C5.5
It sets the machining pass and is programmed with a positive value given in radius. If programmed
with a 0 value, the CNC will display the corresponding error message.
All the machining passes will be run with this step, except the last one that will remove the residual
stock.
D 5.5
It sets the safety distance the tool withdraws after each pass.
When programming D with a value other than 0, the cutter withdraws at 45º until reaching the safety
distance (left figure).
When programming D with a 0 value, the exit path is the same as the entry path. This may be useful
to groove complex profiles, to use these cycle on cylindrical grinders, etc.
