Code definition:
X_ C_ or Z_ C_ It is the hole position data and is valid only in the specified block.
Z(W)_or X(U)_ It specifies the coordinate value of hole bottom by using absolute
coordinate , or specifies the distance from point R plane to the hole
bottom by using incremental value, and it is valid in the specified block.
R_ It is the distance from the initial plane to point R and is specified by
radius value with direction. Its unit and range is shown below.
P_ Hole bottom pause time. Unit of ISB system is 1ms and ISC is 0.1ms.
F_ Cutting feedrate.
K_ Execution times of program
（
if neccessary
）
.
M_ M code for clamping C axis （ if neccessary ） .
