1, by what is the manufacturing cost that the mould makes comprised partly? Answer: Say roughly, the distributinging situation of cost is as follows: Cutting 65 ％ , workpiece material 20 ％ , heat treatment 5 ％ , assemble / adjust 10 ％ . The value that the economy with the metallic cutting performance with this very clear also upper good palpability and good overall cutting right solution produces. 2, what is a mould in making main, common treatment working procedure? Answer: Make should pass cutting course, among them at least part of one's job is type of 3 working procedure: Rough machining, semifinishing machining and finish machining, still have superfinishing even sometimes (it is application of high speed cutting for the most part) . Incomplete surplus milling prepares for finish machining after semifinishing machining working procedure of course. Answer hard to achieve the surplus that leaves to distributing equably for next working procedure in each working procedure, this are very important. If the direction of cutting tool method and working load have rapid change rarely, the life of cutting tool is lengthened possibly, can forecast more. If likelihood, answer to have finish machining process on special machine tool. This meeting is in debug and assemble the geometrical precision that rises inside time and quality more shortly. 3, should basically use in these different process why to plant cutting tool? Answer: Rough machining working procedure: Head of milling cutter of round razor blade, ball stands milling cutter and radius of circular arc of big point of a knife establish milling cutter. Semifinishing machining working procedure: Milling cutter of round razor blade (diametical limits is 10 - the milling cutter of round razor blade of 25 Mm) , ball head stands milling cutter. Finish machining working procedure: Head of milling cutter of round razor blade, ball stands milling cutter. Remains measures milling working procedure: Head of milling cutter of round razor blade, ball stands milling cutter, erect milling cutter. Through choosing form of technical cutting tool measure, chamfer and brand combination, and cutting parameter and right milling strategy, will optimize cutting craft, this is very important. 4, to obtain optimum behavior, how should milling cutter locate? Answer: Cutting length can get the influence of milling cutter position. The cutting length that cutting tool life often must assume with cutting blade is concerned. Be located in work center milling cutter surely its cutting length is short, if make milling cutter is in,assume route of center of one direction deviate, the arc of cutting is long. Want to remember, cutting force is how of action, must achieve eclectic. Below the center circumstance that is located in workpiece surely in cutting tool, when bit cutting blade is entered or exiting cutting, the direction of radial cutting force is changed subsequently. The clearance of machine tool main shaft also makes oscillatory aggravate, bring about bit vibration. Through making in the center of cutting tool deviate, can get be mixinged constantly favorable cutting force direction. Dangerous extend longer, the vibration that overcomes all likelihoods is more important also. CNC Milling
