A cutting suppression treatment method derived from the surface texture of the rake face of a micro turning tool

Abstract

The invention relates to a micro lathe tool front tool face surface texture derivative cutting suppression treating method, and belongs to the technical field of tools. By means of the method, througha nanosecond pulse laser and micro electric spark composite machining means, a nanosecond pulse laser device is firstly used for machining a micro texture on the surface of a micro lathe tool; then atool sample obtained after laser treating is installed under a micro electric spark treating device; a micro electric spark electrode is subjected to finishing according to the set shape, the electrode obtained after finishing conducts edge rounding treatment on the micro texture of the surface of the tool, and the micro texture having edge smooth transition is obtained; and the derivative cutting effect brought by a traditional micro texture is effectively avoided in actual micro cutting machining. Compared with an untreated micro-texture lathe tool, fluctuation in the cutting process can beimproved during micro cutting machining, the cutting force is reduced, the cutting form is changed, the inflow and outflow state of cutting chips in a micro pit is improved, and the friction reduction effect of the micro texture is further improved.

Description

technical field [0001] The invention belongs to the technical field of cutting tools, and in particular relates to a cutting inhibition treatment method derived from the surface texture of the rake face of a miniature turning tool. Background technique [0002] The derivative cutting effect is the phenomenon that the micro-texture acts as a cutting edge to cut the workpiece or chips during the cutting process, also known as secondary cutting. Due to the sharpness of the micro-texture edge, during the cutting process, when chips and the machined surface come into contact with the micro-texture, the derivative cutting effect causes instantaneous cutting force fluctuations, the processing stability decreases, the micro-texture gradually wears out, and eventually fails, resulting in The quality of the machined surface is reduced. [0003] At present, a large number of studies have shown that through the reasonable arrangement of micro-texture on the surface of the tool, the cut...
