2. Format
The bevel cutting compensation function is active during the bevel cutting mode. The bevel cutting
compensation function manages the procedure of fixed nozzle continuously by using the arithmetic
2nd arm length depend on the bevel angle.
The bevel cutting mode is cancelled by also Reset.
Parameter No.15616 and 15619 must be set before the bevel cutting mode is started. Parameter
No.15616 is set the real 2nd arm length (L in Figure 3) and parameter No.15619 is set offset
length from nozzle tip to tool center point (H in Figure 3). Parameter No.15619 can be set by using
G71 R_ command before G71 P1 command.

- Page 21. Outline In most case of bevel cutting, the tool center point (TCP) of the fixed nozzle (Attitude control-B function) is set on the bottom side of workpiece. When the bevel angle is changing continuously, the nozzle rotates around this TCP. (Figure 1) Therefore, the nozzle would have a collision w
