Abstract
An estimated force applied by a milling tool at a surface point of a component is determined during milling operations of the component. An estimated deflection of the component associated with the estimated force is determined using the estimated force and a compliance tensor of the component corresponding to the surface point of the component. The estimated deflection of the component is compared to one or more deflection criteria. A feed rate of the milling tool is adjusted during the milling operations of the component based on results of the comparing.
Claims20
A method comprising:
- determining, during milling operations of a component, an estimated force applied by a milling tool at a surface point of the component;
- determining, using the estimated force and a compliance tensor of the component corresponding to the surface point of the component, an estimated deflection of the component associated with the estimated force;
- comparing the estimated deflection of the component to one or more deflection criteria;
- and
- adjusting, during the milling operations of the component, a feed rate of the milling tool based on results of the comparing.
A milling machine comprising:
- a milling tool configured to remove material from a component during milling operations;
- a control system configured to control a feed rate of the milling tool during the milling operations;
- one or more processors;
- and
- computer-readable memory encoded with instructions that, when executed by the one or more processors, cause the milling machine to:
- determine an estimated force applied by the milling tool at a surface point of the component during the milling operations;
- determine, using the estimated force and a compliance tensor of the component corresponding to the surface point of the component, an estimated deflection of the component associated with the estimated force;
- compare the estimated deflection of the component to one or more deflection criteria to produce deflection comparison results;
- and
- provide control commands to the control system to cause the control system to adjust the feed rate of the milling tool during the milling operations based on the deflection comparison results.
