Publication number: 20190047105Abstract: 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.Type: ApplicationFiled: August 8, 2017Publication date: February 14, 2019Inventors: Raja Kountanya, Daniel Gynther, Ronald A.
