2、ality System 质量体系4.0 Content: 内容4.1 ObjectiveStandardize CNC machinists to operate CNC machines. CNC数控机床操作规范。4.2 ScopeCNC work procedureCNC工作程序。4.3 EquipmentMachine: Makino S33, DMG 63v机器型号：Makino S33, DMG6 3v4.4 Work requirementEnsure the plate consistent with design drawings.确保模板与设计图纸相符。4.5 Check
3、the materialThe material of plate is same as the label of drawing.模板材料与图纸相符。4.6 Check the machine and machining conditionEnsure to return zero in X, Y, Z axis.Ensure enough cooling oil, lubricant in spindle and slides.Clean the fixture, parallel bars and table. Ensure their flatness within 0.01mm/10
4、0mm. Put the plate on the parallel bar and lever it. Clamp the plate and check again the flatness.确保XYZ轴归零。确保足够冷却油滑轨润滑及其，清理工作台治具，确保平面度在0.01mm/100mm。放置工件于工作台，夹紧后再次检查平面度。4.7 Maintaining of machine.Timely finish machine point inspection, and fill out the form.及时完成机器点检规定内容，并填写表单。Calibrate machines.设备矫正。
5、4.8 Operating method4.8.1 Input the program, as the sign INPUT “” disappears from the monitor of machine, it mean the input complete. 输入相关的加工程序，当“INPUT”从机监视器消失，这意味着输入完整。4.8.2 Check the flatness of plate on the machine table; ensure its difference is less then 0.1mm before grinding. 检查平面度，确保研磨前其差异小于0
6、.1毫米。4.8.3 Understand the drawing. Check whether it is not clear or whether there is the command of return zero in program. 理解图纸，检查是否有不清楚的地方，是否有归零指令。4.8.4 Set up cutters order according to machining process table, and then align the cutters. While the alignment, the start point of cutter should be o
7、ver 50mm from top of work piece. It is safe for operation.设置加工刀具顺序按照进程表，然后对齐刀具。虽然对齐，刀具的起点应在工件上从50毫米。这是操作安全。4.8.5 Check the Datum on plate is same as the drawing.请检查模板基准与图档设置一致。4.8.6 Hide the subprograms, run the main program to check the tool change is right.隐藏子程序，运行主程序检查换刀是否正确。4.8.7 Recover the sub
8、programs, run from tool T1, take care the initial engage and prevent the wrong setting of program to damage the machine.恢复子程序，run刀具T1,注意最初的边，防止错误设施损坏设备。4.8.8 For drilling of big hole like as guide pin, do not drill with big driller, should be cut layer by layer. The depth of per layer is 0.20.3mm fo
9、r roughing and 0.050.1mm for finishing.Caution: This is for preserve the accuracy of machine. Machine running is in high speed and is precision. Be Suitable to cut with high speed and low remove rate.钻大孔的时候比如导柱孔，应该一层层的切削，每一层0.20.3mm。直到精加工完成。4.8.9 For WEDM hole, the real cutting diameter has to be sm
10、aller 1.0mm than the request on the drawing whatever drilling or milling.对于后续线割孔，应保留加工余量，无论是钻还是研磨。4.8.10. After complete the all program, check the datum. Check the used cutters ensure there no damage or waste.当完成所有程序，检查基准是否移动，查看刀具是否有损坏。4.8.11 According to the design drawing, check the relative dime
11、nsion.按照图纸检查相关尺寸。4.9 Requirement of safety and protect:按规定，做好防护。The compensating value H of the cutter should be correct and unanimous with cutter number.H补偿值应该正确Confirm the cutter and plate is fix.确认刀具跟工件是否夹紧。Check the initial engage.检查初始边。For emergency, press the button “EMG”.紧急情况按下紧急开关。5.0REVISION HISTORY O 11-02-2010 initial release of the procedure.
