Fig. 14.7 (a) Machining Drawing (example)
For command a straight line, specify one or two out of X, Z, and A.
If only one is specified, the straight line must be primarily defined by a
command in the next block.
To command the degree of a straight line or the value of chamfering or
corner R, command with a comma (,) as follows :
, A_
, C_
, R_
By specifying 1 to parameter CCR No. 3405#4 on the system which does
not use A or C as an axis name, the degree of a straight line or the value
of chamfering or corner R can be commanded without a comma (,) as
follows :
A_
C_
R_
