CNC machining center analysis and determination of complex parts processing technology
The CNC machining center can handle the machining problems of some precision parts.The precision parts processed are very delicate,and the errors and problems appear less.How does the cnc machining center do it?CNC machining center analyzes and determines the processing of complex parts.Process.
1,determine the part blank
For complex parts,it is necessary to select the blank according to the process design of the part before processing.The selection of the blank mainly refers to determining the type of the blank,the manufacturing method and the blank size after the margin is determined.If the material of the complex part is steel,it is necessary to deburr the complex part according to the technical requirements,so that the shape of the part is kept smooth and beautiful.
The blanks of complex parts require the choice of treated steel,as the treated steel has a higher hardness and is more suitable for machining.In addition to processing the blank and the size of the part,the other parts can be processed in one part.
2,determine the positioning criteria of complex parts
During the machining process,when selecting the rough reference,it is necessary to consider how to ensure sufficient margin for each machining surface to ensure the surface processing size and position requirements are qualified.Therefore,the rough reference selected in general processing is mostly the plane of the blank.According to the processing of the concave table,the processing requirements of the hole,the positioning reference will select the bottom surface of the bottom plate.
3.Develop complex parts routing
In the processing,when selecting the rough reference,it is generally considered to ensure that there is sufficient margin for each machining surface.According to the processing of the concave table,the processing requirements of the hole,the positioning reference selects the bottom surface of the upper pressure plate.
When processing complex parts,the machining route includes selecting the machining method,dividing the machining stage,dividing the process,scheduling the machining sequence,and determining the feed route.Therefore,it is important to determine the process of CNC machining of complex parts.
