Response with REPOS
If an SAR cycle is interrupted and repositioned, it resumes at the point of interruption on RMI.
With RME, the contact point is the end point of the last SAR block; with RMB, it is the start
point of the first SAR block.
If RMI is programmed together with DISPR (reapproach at distance DISPR in front of
interruption point), the reapproach point can appear in a subblock of the SAR cycle before
the interruption subblock.
2.4.4.6 Examples
Example 1
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)
