W1: Tool offset

18.5 Tool radius compensation 2D (TRC)

Examples

The following conditions must be true:

Smooth approach is activated in block N20

X=40 (end point); Y=0; Z=0

Approach movement performed with quadrant (G247)

Approach direction not programmed, G140 is valid, i.e., because TRC is active (G42) and compensation value

is positive (10), the contour is approached from the right

Approach circle generated internally (SAR contour) has radius 20, so that the radius of the tool center path is

equal to the programmed value DISR=10

Because of G341, the approach movement takes place with a circle in the plane, resulting in a start point at

(20, -20, 0)

Because DISCL=5, point P2 is at position (20, -20, 5) and, because of Z30, point P1 is in N10 at (20, -20, 30)
