Figure 18-30 Example: Inside corner with TRC without contour violation (predicting 3 blocks)
Special points to be noted
Where multiple intersections with the next block are found, the intersection nearest the start of the next block
applies.
18.5.8 Collision detection and bottleneck detection
Collision detection
Collision detection (bottleneck detection) examines whether the equidistant paths of non-consecutive blocks
intersect. If an intersection is found, the response is the same as for inside corners with multiple intersections:
The last intersection to be found is valid:
The maximum number of blocks used for the predictive check can be entered in the machine data:
MD20240 $MC_CUTCOM_MAXNUM_CHECK_BLOCKS (blocks for predictive contour calculation for TRC).
