The Method of Determining the Conditions for Machining Thin-Walled Parts

The specifics of machining thin-walled parts is analyzed in the article with a focus on an increased risk of rejection rates due to the deformation of the parts under cutting and gripping forces. This problem is current for the aerospace industry where thin-walled parts are used to reduce the weight of aircraft. At present, this issue is not sufficiently studied and requires further research. The main approaches to defect-free machining of thin-walled parts are considered. Special attention is given to the options available for effective preparation of the machining process with minimal material and operational expenditure. One of the key components in realizing such options is mathematical prediction of expected technological deformations using special software packages. Using ANSYS software, a calculation for turning a part gripped in a three-cam holder is given as an example. A general algorithm is proposed for determining technological conditions when elastic-pliable parts can be machined without exceeding permissible tolerances.
