Methods and systems for calculation of feedrate

摘要

Methods and systems for calculating a feedrate for programming a multi-axis machining tool. For at least one control block in a defined machining path: a displacement of a defined machine control point from a previous control block to a current control block is determined; a displacement of a defined feedrate control point from the previous control block to the current control block is determined; a compensation ratio is calculated as a ratio between the displacement of the defined machine control point and the displacement of the defined feedrate control point; and a feedrate for the machine control point is calculated by applying the compensation ratio to a desired feedrate. The calculated federate is used in a control block of a multi-axis machining tool.

1. A method for calculating a compensated feedrate based on a feedrate control point from a desired feedrate calculated based on a machine control point for programming a multi-axis machining tool, the method comprising:
for at least one control block in a defined machining path:
determining a displacement of the machine control point from a previous control block to a current control block;determining a displacement of the feedrate control point from the previous control block to the current control block, the feedrate control point comprising a contact point between the tool and a workpiece;calculating a compensation ratio as a ratio between the displacement of the machine control point and the displacement of the feedrate control point; andcalculating the compensated feedrate for the machine control point by applying the compensation ratio to the desired feedrate; and using the calculated compensated feedrate in the at least one control block of the multi-axis machining tool.
