The axis word can exist repetitively in the same block and the later value is valid, but when
No.3403 Bit 6 (AD2) is set 1, the alarm occurs. U, W in other G command has bee specified to others.
For example: in G73, the above conditions
1.4.2 Diameter programming and radius programming
Because the workpiece section is the circle in CNC turning controlled program, X dimension can
use two kind of method; diameter programming command and radius programming command.
1. The user can select the radius programming or diameter programming, which is set by state
parameter (No. 1006 Bit 3(DIAX)).
2. Parameters related to diameter/radius programming:
State parameter No.1006 BIT3 (DIAx):
0—radius programming
；
1—diameter programming ；
State parameter No.5004 Bit1(ORC):
0—offset value is expressed with diameter;
1—offset value is expressed with radius;
Pay more attention to the conditions in the following table when X uses diameter programming:
