Tool cathode provided with tool setting device and tool setting method of tool cathode

Abstract

The invention relates to a tool cathode provided with a tool setting device and a tool setting method of the tool cathode and belongs to the field of electrolytic milling and grinding combined machining. The tool setting device comprises a pressing block, a tool setting block, positioning polished rods and a fastening screw; a flange is arranged on the outer side of the middle of the tool cathode;through holes are formed in the flange; and the tool setting block is made of a stainless steel material. During tool setting, two ends of a multimeter are connected with the tool setting block and aworkpiece respectively, whether the distance between the tool setting block and the workpiece is zero is judged through mutation current produced through contact between the tool setting block and the workpiece, and the distance between the tool cathode and the workpiece can be calculated according to the thickness and the height of the tool setting block, the height of the flange of the tool cathode and the known thickness of an abrasive particle layer, so that tool setting is completed. The tool setting device is utilized and is simple to operate, convenient to disassemble and high in toolsetting precision, and the defect of poor tool setting precision of a traditional tool setting method adopting a filler gauge is overcome.

Description

technical field [0001] The invention relates to a tool cathode with a tool setting device and a tool setting method thereof, belonging to the field of electrolytic milling and grinding compound processing. Background technique [0002] With the development of production technology, some difficult-to-cut alloys such as titanium alloys and high-temperature alloys have been used more and more in aerospace and other fields. For example, the weight of titanium in the American SR-71 high-altitude and high-speed reconnaissance aircraft with a flight Mach number of 3 accounts for 93% of the weight of the whole machine, and the amount of GH4169 in the PW4000 engine accounts for 57% of the total mass. However, due to the large size, complex features, and thin structure of aircraft parts, there is a high material removal ratio from the blank to the part. When using traditional machining methods, the cutting force is large, the cutting temperature is high, and the tool wears quickly. T...
