Trial cutting method The tool setting method is simple, but it will leave marks on the workpiece, and the tool setting accuracy is low. Some parts are not suitable for trial cutting due to special restrictions
The visual tool setting method is a very rough tool setting method, the accuracy is not high, and it is easy to damage the micro-milling cutter. It is suitable for parts without a reference edge or with a large blank margin, but it is not suitable for precision tool setting in micro-milling.
The accuracy of the tool setting method using the dial indicator is affected by the accuracy of the dial indicator, and the tool setting process is cumbersome

Description
technical field [0001] The invention belongs to the technical field of micro-milling processing, and particularly relates to a micro-milling tool setting detection circuit and a micro-milling tool setting method. Background technique [0002] As one of the key technologies in the field of micro-machining, micro-milling is often used for local high-precision machining and micro-scale structure machining in high-precision components. Micro-milling technology has its unique advantages in machining micro components with complex three-dimensional structures. From the analysis of the processing mechanism, the micro-milling process is through the high-speed rotation of the micro-milling tool and the continuous feeding of the spindle to remove the excess material on the workpiece to achieve the purpose of micro-topographic feature processing. The accuracy of micro-milling is mainly affected by the shape of the micro-milling tool, the feed per tooth, the spindle speed and the tool se...
