3.11.2 Circular Chamfering
Circular chamfering: insert one circular between linear contours, circular contours, linear contour
and circular contour, the circular and the contour line are transited by the tangent. The command of
circular chamfering is D, and the data behind the command is the radius of chamfering circular. The
circular chamfering must be used in G01, G02 or G03.
1). Linear to linear
Command format:
G01 X(U)_ Z(W)_ D_;
G01 X(U)_ Z(W)_;
Command function:
insert one circular between two straight lines, the inserted circular
block and two straight lines are tangent, the radius is the data behind
the command address D.
2). Linear to circular
Command format:
G01 X(U)_ Z(W)_ D_;
G02/G03 X(U)_ Z(W)_ R_;
or
G01 X(U)_ Z(W)_ D_;
G02/G03 X(U)_ Z(W)_ I_ K_;
Command function:
insert one circular between linear and circular, the inserted circular is
tangent to the linear and the circular, and the radius is the data
behind the command address D.
