Program: O0002
G00 X100 Z50
；
G66 P0100 L2 A2 B20 C20 I30 J20 K20
；
execute the block instead of call, writing local
variables, but only change the mode
G01 X80 Z50
；
after executing the block, call No.P0100 program two times(refresh the local
variable according to the argument)
G0 U0 W0; have no subprograms to be called
G01 U1; after executing the block, call No.P0100 program two times(refresh the
local variable according to the argument)
G67
；
G66 mode call is cancelled
G01 X20 Z50 ； after executing the block, the system does not call No.P0100 program

2.28 Slant Axis Control
The slant axis control function is defined that the slant axis relative to a quadrature axis is installed
with exceeding 90°, which makes each axis’ movement amount be controlled according to a slant
angle.
Distribute any axes to one group of slant axis and quadrature axis by a parameter.
The actual movement is controlled according to a slant angle, but, a program is compiled
according to a vertical intersection between a slant axis and quadrature axis. Here, the used
coordinate system is called a program coordinate system. (the following contents sometimes
changes the program coordinate system into a cartesian coordinate system, but the actual movement
coordinate system is called a slant coordinate system or a machine coordinate system.)
