Processing pla n formulation The division working procedure needs to consider to the production scale, the processing precision, uses the engine bed the character istic, the static load situation and so on. The division working procedure ma y have two kind of trends: The working procedure centralism and the working procedure are dispersible. The working procedure centralism disperses has its strong point respectively, in genera l, by enhances the productivity in the mass production prima rily, must widely use the multi knives, the single axle and multiple spind le is automa tic or the semia utoma tic engine bed, multiple spind le pla nertype milling machine, aggregate machinetool and so on, therefore adopts the working procedure centralism to be possible to obtain the prominent effect. In this design bearing seat drill hole aggregate machinetool very great degree causes various working procedures to concentrate as far as possible, the displa y aggregate machinetool mer it, at the same time causes each kind of error to reduce to the threshold. Because in this design processes in the ponents 10 holes the partial holes are away from too near, is not advantageous for the processing, therefore separates is two locations pletes, then carries on the ponents position transformation. Below the ma in location selects the pla n after the analysis: 1) loads and unloads, cla mps。 2) drills 7 holes 。 4) drills crosswise hole f14。 6) attacks the silk. 2 pound cutting tools cutting specificationses putation specifications character istic The aggregate machinetool norma l work and reasonably selects the cutting specifications, namely the determination reasonable cutting speed and the work enters to the quantity has the very big relations. The cutting specifications elects the inappropriateness, can cause the aggregate machinetool to
