Abstract

The system and method described herein generally pertains to generating a lead in profile that defines acceleration before a cutting velocity is achieved to perform a cutting operation and a lead out profile that defines deceleration after the cutting operation is performed. The lead in profile defines acceleration from approximately zero (0) to the cutting velocity within a duration of time in order to perform the cutting operation, wherein the lead in profile is calculated based on the cutting velocity or a type of material of the workpiece, a start location for the cutting operation, and a thickness of the workpiece. The lead out profile defines deceleration from the cutting operation to approximately zero (0) within a duration of time, wherein the lead out profile is calculated based on the cutting velocity or a type of material of the workpiece, an end location for the cutting operation, and a thickness of the workpiece.

First claim

What is claimed is:

a lead component that is configured to generate a lead in profile for controlling an acceleration of the cutting tool during an acceleration time period prior to the shape cutting or marking operation and a lead out profile for controlling a deceleration of the cutting tool during a deceleration time period after the shape cutting or marking operation; and
a motion control component that is configured to control a movement of the cutting tool based on the shape cutting profile with the one or more geometric coordinates and configured to control a velocity of the cutting tool based on at least the lead in profile,
wherein the lead in profile defines an end point of the acceleration time period such that the shape cutting or marking operation starts at the end point of the acceleration time period.

2. The system of claim 1 , wherein:
the lead in profile is generated based on a cutting velocity used during the cutting or marking operation and a start location in 2 dimensional (2D) space of the desired shape for the workpiece; and
the lead out profile is generated based on the cutting velocity used during the cutting or marking operation, an end location in 2 dimensional (2D) space of the desired shape for the workpiece, and an amount of inertia.

3. The system of claim 1 , wherein the cutting or marking of the workpiece is at least one of a plasma cutting operation or a plasma marking operation, respectively.

4. The system of claim 1 , wherein the cutting or marking of the workpiece is at least one of a laser cutting operation or a laser marking operation, respectively.
