Abstract

The present invention relates to a method for processing a nylon internal polygon. All surfaces of an internal polygonal hole are orderly cut by common machine processing equipment and a special cutter. The cutting output of a part is from 0.02mm to 0.05mm during the cutting. After one face is cut, an indexing head is rotated for 360 degrees per Newton, the next face of the part is cut, and the other faces of the polygon are processed in the mode. The cutter is a straight handle type or a conic handle type, the width of a cutting edge is equal to the side length of the internal polygon, and a chip removal angle is arranged between the front cutter face and the rear cutter face of the cutter. A front cutter angle (3) is from 8 degrees to 12 degrees. The front angle (4) of a rear cutter angle is from 6 degrees to 10 degrees, and the rear angle (5) is from 9 degrees to 15 degrees. When a part of the internal polygon processed by the method is cut to the internal square root part, the phenomena of whitening part, chip adherence to the cutter, fracture failure, etc due to large cutting quantity and heated materials are avoided. The surfaces of internal square hole are smooth. The present invention has the advantages of high operability, high practicability, low manufacture cost and good product quality.

Description

1. Technical field [0001] The invention relates to the processing of non-metallic materials, in particular to a method for processing nylon inner polygons and a special cutting tool thereof. 2. Background technology [0002] At present, in my country's aviation manufacturing industry, the application of mechanical processing of nylon parts on aircraft has been increasing day by day. Usually, there are two methods for the processing of inner polygons using traditional manufacturing techniques: first, using a special equipment - a slotting machine for one-time inserting and cutting; second, manufacturing by manual filing. If the cost of purchasing a special slotting machine just to process the polygon inside the part is too high, it will directly affect the economic benefit; and when the method of file repair is used for processing, due to the characteristics of the nylon material itself-grinding or file repair will cause the processed surface to become rougher and rougher. A...
