Research on Machining Deformation of Miniature Thin-Plate Parts in Milling

The machining deformation of the sewing-needle body that is the typical miniature thin-plate part is analyzed. The result demonstrated that not only one kind of stress occurred in the milling of sewing-needle part. The magnitude of cutting force is an important parameter determined the extent of machining deformation. The experimental test of the milling cutting force is developed. The cutting force and the mode of milling can influence the dimension changing that resulted the dimension error.
