Five Basic Methods for Controlling Over cutting and Under cutting in Milling of Precision Parts
In the process of machining precision parts, over cutting and under cutting of metal cutting is one of the difficulties that must be controlled to improve machining accuracy.

The basic method of controlling over cutting and under cutting in milling process must pay attention to the following five points:
(1) Improve the rigidity of the process system, and avoid elastic deflection and pulling between milling cutter, fixture, machine tool and workpiece.
(2) Control the appropriate and minimum milling allowance to avoid excessive allowance causing over cutting by pulling or under cutting by deflection, and avoid the comprehensive phenomenon that excessive allowance causes under cutting due to difficult cutting and over cutting after additional allowance.

(3) Control the wear degree and service life of the milling cutter. When it is necessary to control the machining accuracy and the allowance is relatively small, the milling cutter at the initial stage of normal wear should be used.
(4) In the process of milling, pay attention to exploring the working shape, rigidity, material removal, cutting parameter selection, milling method and other related laws, and use the most stable milling scheme for processing.
(5) Attention shall be paid to the method of eliminating under cutting allowance after multiple cleaning at the original predetermined position to meet the requirements of geometric accuracy of milling.
It is very important to carry out the correct control method in the milling process of precision parts, otherwise it will lead to the birth of a large number of defective products and waste a large number of materials. To ensure the processing quality, we must strictly follow these five basic methods to improve the processing quality.
