2.4.12
Intersection procedure for polynomials
Function
If two curves with active tool radius compensation form an outside corner, depending on the
G code of the 18th group (corner behavior with tool compensation;
G450
/
G451
) and
regardless of the type of curves involved (straight lines, circles, polynomials):
•
Either a conic is inserted to bypass the corner
Or
•
The curves involved are extrapolated to form an intersection.
If no intersection is found with
G451
activated, or if the angle formed by the two curves is too
steep, switchover to insert mode is automatic.
The intersection procedure for polynomials is released with the machine data:
MD20256 $MC_CUTCOM_INTERS_POLY_ENABLE (Intersection process possible for
polynomials).
Note
If this machine data is set to inactive, a block (can be very short) is always inserted (even if
transitions are almost tangential). These short blocks always produce unwanted drops in
speed during
G64
operation.
