Appeal No. 2002-1050
Application 09/425,505
1. A method of cutting planar production material with a
controlled cutting machine having a cutting tool with a tool tip
and which machine moves the tool in response to control data
defining commanded cutting paths, said method comprising the
steps of:
performing cutting tests on various planar test materials
with the cutting machine under selected cutting conditions using
test control data defining commanded test cutting paths whereby
deflection forces are produced on the tool due to the interaction
of the tool and materials so as to cause the tool tip to move
along actual test cutting paths laterally offset from the
commanded test cutting paths, and determining compensating
lateral directional offsets needed to align the actual test
cutting paths with the commanded test cutting paths;
establishing a schedule of the compensating lateral
directional offsets needed to align the actual test cutting paths
with the commanded test cutting paths as determined by the
cutting tests, the schedule to be repeatedly used thereafter for
cutting planar production material having cutting conditions
associated with the schedule; and
cutting planar production material thereafter by advancing
the cutting tool and planar material relative to one another with
said machine operating in response to production control data
defining commanded production cutting paths and using said
schedule of compensating lateral directional offsets to modify
the production control data to cause the paths followed by the
cutting tool to be said commanded production cutting paths.
