3.10 Cylindrical Interpolation G7.1
Command function ： 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(below).
Command format ： G07.1 Cc ； （ enable/cancel cylindrical interpolation mode ）
Cc: the radius of the cylinder
；
Radius ≠ 0
：
starts the cylindrical interpolation mode
Radius
＝
0
：
cancels the cylindrical interpolation mode

A coordinate command from starting the cylindrical interpolation mode to
completing its cancellation is a cylindrical coordinate system;
G07.1 Cxxxx(cylindrical radius value)
；
……starting the cylindrical interpolation
…… ；
……
；
………The coordinate command in the range is a cylindrical
coordinate system
……
；
G07.1 C0 ； ……cancel the cylindrical interpolation

G7.1 is non-modal
；
（ 3 ） The cylindrical interpolation mode is cancelled in power-on and reset;

）
The rotary axis executes a program by an angle, a rolling function of a rotary
axis in the cylindrical interpolation mode will be automatically invalid, and a
programming command value must be more than 360
0
when the interpolation
range is more than one circle;

The coordinate value can be absolute or incremental;
（ 6 ） The tool nose radius compensation G41, G42 can be executed and their tool
nose directions are 0
；
（ 7 ） A feedrate specified in the cylindrical interpolation mode is a speed on the
developed cylindrical surface, its unit: mm/min or inch/min
；
