Dimension is tagged complete, outline description is clear. Hardware data is 45, without heat treatment and hardness requirement. Nextpage2, craft is analysed 1, treatment means 1) on the design given the dimension with higher demand of a few precision, because its are fair difference is numeric and lesser, average need not be taken when reason process designing, and take its entirely basic measure but. 2) workpiece treatment needs to decide ordinal treatment finishs Zun Duan, assure overall length dimension. 2, the fixed position that hold clip is shown 1 times like the graph, it is fixed position with semifinished product axes fiducial.

Graph 2 coordinate origin 5, solid example note 1) must undertake according to the regulations system of numerical control workshop outfit of numerical control solid example, move wants to accord with a requirement strictly, 2) every student must stand fast post, do not allow to string together hillock casually, 3) when solid example must punctual have solid standard to solid example workshop, do not allow to be late with leave early. 4) the environment that should maintain center of good numerical control during solid example is wholesome, after using a machine tool, should sweep the spot and wipe a machine tool. 5) when installing work semifinished product, want to notice clamp semifinished product, prevent to trying the semifinished product when cutting to become loose, bring about attaint cutting tool. 6) the alternative that cutting dosage always should note when treatment and control, find out the most appropriate cutting parameter. 7) the dimension that control spare parts should fill through the knife when be being machined. 8) when desired effect, the solecism that should check an order and position of spot taking a knife are correct. 9) the burr that part of arris of edge of purify spare parts wants after treatment.
