3.11 Chamfering Function
Chamfering function is to insert one straight line or circular between two contours to make the tool
smoothly transmit from one contour to another one. GSK980TDi uses the linear and circular
chamfering functions.
3.11.1 Linear Chamfering
Linear chamfering: insert one straight line in the linear contours, arc contours, linear contour and
arc contour. The command address of linear chamfering is L, behind which data is the length of
chamfering straight line. The linear chamfering must be used in G01, G02 or G03 command.
Linear chamfering divides into two types, two types are mainly distinguished from the different
definitions of the command value L in the program, one is L chamfering length, the other is length
between the chamfering point and intersection point, which can be selected by state parameter
No.181.0. In the following explanation, type I represents that L is chamfering length; type II is the
length between the chamfering point and intersection point.
