∆V :Cutting point compensation value (∆V2 - ∆V1) for
movement of ¢L
∆V1 :C-axis component of the vector normal to N1 from the
center of the start point of ∆L
∆V2 :C-axis component of the vector normal to N1 from the
center of the end point of ∆L
R :Arc radius
Fig.4.10 (c) Cutting Point Compensation in a Circular Command Block
(3) When cutting point compensation is not applied between blocks
When, as shown in Fig.4.10 (d) andFig.4.10 (e), the cutting point
compensation value (V in the figures) is less than the value set in
parameter No. 6112, one of the operations below is performed.
(The operation that is performed depends on the setting of bit 6
(CYS) of parameter No. 6004.
1) When bit 6 (CYS) of parameter No. 6004 is set to 1
Cutting point compensation is not applied between blocks N1
and N2, but is applied when block N2 is executed.

Tool center path
V FC-axis component of C1 - C0
C0 FCutting surface at the start point of block N1
C1 FCutting surface at the end point of block N1
