CNC machining should learn to operate according to machining characteristics
The process design of Shenzhen CNC precision processing plant must be completed before the programming is started, because the programming is based only after the process plan is determined. The quality of the process plan will not only affect the efficieCNCy of the machine tool, but also directly affect the processing quality of the parts. Analyze according to a large number of machining examples. Inadequate consideration of process design is one of the main reasons for CNC machining errors
Therefore, it is very necessary to make process analysis and planning before programming. CNC machining process design mainly iCNCludes the following contents:
(1) Select the parts suitable for machining on the CNC machine tool, and determine the process content
(2) Analyze the drawings of the parts to be processed, define the processing content and technical requirements, and determine the processing scheme of the parts. Formulate CNC processing route. Such as division of processes, connection between processing and non CNC processing processes, etc
Machining workpiece
(Processing workpiece)
(3) Design of processing procedures and steps. For example, the positioning datum of the selected parts, the determination of the fixture and auxiliary equipment scheme, the determination of the cutting parameters, etc.
(4) Adjustment of CNC machining program. Select tool setting point and tool change point, determine tool compensation, and determine processing route
(5) Allocate machining allowaCNCe in CNC machining.
(6) Process some process instructions on CNC machine tools.
(7) First article trial processing and on-site problem handling.
