Reasonable cutting tool type selecting machines a method with what optimize, it is very important to be led to heightening treatment effect and prolong cutting tool life, be especially when component of aviation of material of treatment difficult treatment is more important. Cutting tool of a kind of high quality difficult treatment material, must have the exterior coating that exceeds matrix of fine grain cutting tool, sharp cutting angle, strong cutting point, heat-resisting to wait. Above all, sufficient refrigeration, proper treatment linear velocity, effective break bits, reasonable cutting tool to include part very effective to controlling temperature of point of a knife. To be being had at the same time inside cooling CNC machine tool and cutting tool, should use as far as possible most benefit at what drop in temperature inside cooling function, so that make strong high-pressured flow takes away many heat in metal cutting, ensure treatment area maintains inside certain temperature limits. Although do not have inside the machine of cooling function machines equipment, outside also suggesting to use, pass inside cooling knife handle, heighten cooling pressure at the same time, improve cooling result. Next, control the cutting force of cutting tool and cutting rate appropriately, also be to reduce treatment area temperature, lengthen one of methods with cutting tool the most effective life. The cutting tool point that machines difficult treatment material to all use essence of life to grind commonly normally, lesser cutting deepness and cutting width. The element such as structure of the difficult treatment material with different basis, spare parts and treatment facilities, it is very important to choose sound cutting linear velocity. In be machined normally nickel radical alloy should be controlled in 20~50m/min, titanium alloy should be controlled in 30~110m/min, PH stainless steel should be controlled in 50~120m/min. The 3rd, to same machine tool and spare parts, the method that processes difficult treatment data can affect the treatment efficiency of cutting tool and cutting tool life greatly. No matter be to use interpolation of cycloidal treatment, helix and means of big feed milling, its purpose is to reduce cutting force, reduce cutting area temperature. Cycloid cuts a way but utmost reduces cutting area, make the part of actual cutting bag of cutting tool the smallest, lengthen cutting tool of every tine medicinal powder interpolation of helix of hot time; makes amount of every tine cutting relatively even, handle way of cutting of big feed of most apparent; in corner especially, reduced cutting force effectively with cutting deep, big feed smally, the heat in metal cutting that makes the generation in treatment the youngest, machine area temperature lowest. The 4th, make sure treatment interrupts bits, also be the effective route that controls temperature rise. General generation of many in metallic treatment heat in metal cutting is cutting bits, a large number of heat in metal cutting of the generation in breaking bits effectively to be able to make machine are cut bits is taken away. Normally the circumstance falls, in treatment we do not hope to have the long generation that cut bits. To difficult treatment the treatment of material should notice more, especially to rough machining working procedure, below the condition that in whole treatment systematic tigidity allows, answer to make its produce bit in whole treatment process as far as possible, use the means that go against mill as far as possible, the scrap that makes form by thick attenuate, and scrap appearance is " 9 " glyph, " 6 " glyph or " C " glyph. The 5th, the effective cutting tool that keeps proper in treatment includes part, make each of cutting tool effective treatment ages can utmost ground assures the longest cooling time. Keep proper in treatment, reasonably cutting tool includes part effectively, special the cutting efficiency that is helpful for improving difficult treatment data, lengthen cutting tool to machine life, part of material of difficult to treatment treatment is very important. Cutting tool includes part effectively, mirror to cutting parameter to having immediate concern with Dc of diameter of cutting deepness Ap and cutting width Ae and cutting tool. When processing difficult treatment data especially, answer to avoid full knife cutting as far as possible. In be machined actually, every increase the cutting bag role of cutting tool one times, cutting tool life can decrease about 30% . Anyhow, component of difficult treatment material must have tall hardness, high strenth, tall tenacity and tall wearability, to having stuff of these characteristic new-style difficult treatment, difficulty of difference of function of its machine treatment, treatment efficiency of big, treatment cost of low, cutting tool is high. Come so component of difficult treatment material put forward to machine treatment cutting tool more upland requirement. CNC Milling
