3.8 CYLINDRICAL INTERPOLATION (G07.1)
The amount of travel of a rotary axis specified by an angle is once
internally converted to a distance of a linear axis along the outer
surface so that linear interpolation or circular interpolation can be
performed with another axis. After interpolation, such a distance is
converted back to the amount of travel of the rotary axis.
The cylindrical interpolation function allows the side of a cylinder to
be developed for programming. So programs such as a program for
cylindrical cam grooving can be created very easily.
Format
G07.1 IPr ; Starts the cylindrical interpolation mode
(enables cylindrical interpolation).
:
:
G07.1 IP0 ; The cylindrical interpolation mode is
cancelled.
IP :An address for the rotation axis
r :The radius of the cylinder
Specify G07.1 IPr ; and G07.1 IP0; in separate blocks.
G107 can be used instead of G07.1.
