Narrate through above place, the labor situation order that the spare parts processes has been discharged calm, how to constitute these labor situations process, with respect to need the consideration uses the principle that working procedure is centered or working procedure disperses. (1) working procedure is centered even if center the treatment of the spare parts in a few a few working procedure to finish, content of treatment of every working procedure is much, craft course is short. Its are main the characteristic is: ① can use efficient machine tool and tooling, productivity is tall; ② reduced equipment to amount and jockey everybody are counted and cover an area of an area, save manpower, material resources; ③ reduced workpiece to install a number, benefit at assuring the positional precision between the surface; The tool equipment structure that ④ uses is complex, it is more difficult to adjust maintenance, manufacturing preparation workload is big. (Foreword of day labour of cent of 2) working procedure disperses even if go to the treatment of the spare parts dispersedly inside a lot of working procedure finish, the content that every working procedure machines is little, craft line is very long. Its are main the characteristic is: ① equipment and tooling are simpler, facilitate adjust, get used to the commutation of the product easily; ② is inferior to technical requirement of the worker; ③ can use the most reasonable cutting dosage, reduce motor-driven time; The amount that ④ place requires equipment and tooling is much, jockey person is much, cover an area of an area big. When protocol craft course, working procedure concentration or dispersive degree, basically depend on the structural characteristic of scale of production, spare parts and technical requirement, sometimes, consider each working procedure to produce the consistency of metre even. Usually, odd when pre production, can working procedure concentration, on a general accuracy machine tool treatment goes out as far as possible much surface; Large quantities of mass-produced when, can use the efficient, automatic machine bed such as much knife, much axis already, working procedure concentration, the organization after also can dispersing working procedure sheds water production. Batch production should use the semi-automatic machine tool with taller efficiency as far as possible, make working procedure is centered appropriately, improve productivity effectively thereby. To heavy-duty spare parts, to reduce the amount of labor that workpiece assembles and unassemble and carries, working procedure should be centered appropriately; Poor to tigidity and the nice work with expensive precision, criterion working procedure should disperse appropriately. According to statistic, in the mechanical product of our country, the company with quality productivity of the small lot in belonging to already exceeded 90% of company number, odd in means of small lot production takes absolutely advantage. Gain ground along with what a move in chess or a movement in wushu accuses a technology, in production of the small lot in much breed, use machining center machine tool increasingly, from the point of development trend, apt uses the method that working procedure centers to organize production.
