Abstract:

Cutting deformation is the key factor influencing the precision and quality of the machined thinwalled workpiece, and the form error prediction is the precondition for process optimization and error compensation. Cutting forces are analyzed and cuttingforce model for thinwalled workpiece machining is developed, then a finiteelement model is presented to analyze the surface dimensional errors in peripheral milling of aerospace thinwalled workpieces.
