Corner chamfering, (G39)
7.
(SOFT V02.0X)
133
The programmed chamfering feedrate depends on the type of
movement programmed afterwards:
• If the next movement is in G00, the chamfer will be carried out in
G00.
• If the next movement is in G01, G02 or G03, the chamfer will be
carried out at the feedrate programmed in chamfer definition block.
If no feedrate has been programmed, the chamfer will be carried
out at the active feedrate.
When defining a plane change between the two paths that define a
chamfer, it is carried out in the plane where the second path is defined.
Properties of the function
Function G39 is not modal, therefore, it must be programmed every
time a corner is to be chamfered.
