3.24.1.2 Canned circle explanations
Generally, a canned cycle consists of a sequence of the following operations, see the right figure.
3.24.1.3 G90/G91
The data mode corresponded with G90 and G91 are different. The point R plane and the absolute
position machined at the bottom of the hole are specified by R and Z values, when the command is G 90.
The specified R value is the distance relative to the initial plane, and the Z value is the distance relative to
the R point plane when the command is G91. See the following figure.
