Abstract: A method of cutting planar material (16) with a controlled cutting
machine (10) having a cutting tool (30) with a tool tip (32) includes performing a
cutting test on various planar materials with the cutting machine under selected
cutting conditions which produce deflection forces on the cutting tool due to the
interaction of the cutting tool and materials so as to cause the tool tip to offset and
move along deviated or offset cutting paths (37) relative to desired cutting paths
(33), and determining compensating offsets (300) in order to align and coincide the
actual cutting paths with the desired cutting paths A schedule of the compensating
offsets (300) to align and coincide the actual cutting paths with the desired cutting
paths is established as determined by the cutting tests. The schedule is to be
repeatedly used thereafter for cutting planar material having cutting conditions
associated with the schedule. Planar material is cut thereafter along desired cutting
paths by advancing the cutting tool and planar material relative to one another and
employing the schedule of compensating offsets to control the actual cutting paths to
align and coincide with the desired cutting paths when desired cutting paths and
corresponding cutting conditions arise.
