Research On Electrolytic Passivation Mechanism Of Rotary Tool And Development Of Related Experimental Platform

Many studies have proved the service life of cutter can be prolonged by electrolytic strengthening. Based on the theory of electrolytic strengthening technology, this paper introduced and developed prototype equipment for strengthening cutting edge of rotary cutter and put forward a calculation method of total electric quantity consumption during the electrolysis suitable for microcontroller. The M8 high-speed steel tap is taken as a strengthening example. After finished the strengthening process that it clearly see the results of the surface of tap was obviously polished by observing the micrograph. This equipment improves the reliability of electrolytic strengthening and the cost is relatively cheap.Analysis of cutting force and torque are important for research of taps and its machining process parameters. Based on scientific experimental methods to acquire data, the change of force and torque can be observed in the machining process. Analyzing the influence of different conditions for machining process can improve taps and its parameters to increase productivity. This paper is based on the LabVIEW virtual instrument technology and High-speed steel tap is taken as the example object, cutting force and torque measurement system for taps is introduced for the composition and structure of the software in detail. The machining experiment shows that the system has high-reliability and highaccuracy. And it has been applied successfully to the machining experiment for taps.This paper had already obtained the support from the national natural science fund project“Facing quality integration and the control of high-speed steel tap manufacture & technology research”.The fund number is:51275333.
