One, solid example purpose and requirement (the method that 1) masters grand program process designing; (the basic method that 2) control uses ball of protruding of grand program milling; (body of 3) control control the method of tolerancepublic errand; 2, solid train equipment and preparation of cutting tool of instrument industry capacity are only part drawing date: MG-09, dimension of qualitative 45# of material preparation material 100 × of 100 × 25mm amount 1 2, remarks of amount of unit of standards of measurement of name of classification of serial number of equipment, tool, cutting tool, measure 1 equipment CNC Milling (or machining center) 1 flat-nose pliers of stage 15050mm stage 1 corresponding accessory: Appearance of treatment of this spare parts is simpler, main difficult point consists mill snick area, and use general process designing technology to realize spherical treatment very hard to spherical treatment. And numerical control system thinks besides basic process designing method, user the process designing of this kind of regular curved surface offerred grand program powerful process designing ability, its basically machine regulation for two axes partly, namely random two axes linkage, among them the treatment that one axis makes periodic motion finish curved surface. Clip of outfit of this spare parts is relatively simple, basically machine Mm, Mm and Mm, SR36 Mm, the others dimension asks to did not note dimension common difference dimension compares good control. Should notice the parallelism of the spare parts asks, need to use thick, finish machining and adjust for many times (or make a list) will assure Mm. 3, treatment measure and process semifinished product are 100 × plank of 100 × 25mm, workpiece material is 45# , ask according to part drawing appearance its machine working procedure to be: (1) use flat-nose pliers assembles clip semifinished product, extend exterior 10mm left and right sides; (2) use ф 100 milling cutter the surface on workpiece of mill of thick, essence, the measurement that serves as workpiece is fiducial; Use φ 16 establish milling cutter outline of inside and outside of mill of thick, essence, mm dimension; (3) use φ 10 establish φ of 3- of milling cutter milling 12 aperture. (4) 6 twist drill of use φ get 4- φ 6 aperture. (5) invert workpiece, had adjusted etc tall a height (clip holds 4mm to control) , use flat-nose pliers is placed hold chance to extricateoneself from an awkward position (the size that notes clamping force, prevent to be placed bad) . (6) use φ 16 establish SR36 of milling cutter mill spherical. Attention: Note the size of work clamping force, prevent workpiece to be out of shape, clip is hurt or workpiece flies off. 4, to program (slightly) CNC Milling
