How to determine the feed route during CNC turning?

1. The roughing feed route of CNC Turning uses the Cnc Turning process to rough the workpiece. The commonly used feed routes mainly include the “Rectangular” cycle feed route, the circular feed route along the contour line, the step cutting route and the two-way route. Cutting feed route these several options.

1. The “Rectangular” circular feed path is designed using the rectangular loop function of the CNC system.

2. The circulative feed route along the contour line of the equal distance is to use the closed compound cycle function of the CNC system to control the turning path of the equidistant line cycle along the contour of the workpiece.

3. The bidirectional cutting feed route uses the characteristics of the numerically controlled lathe plus, along the blank outline of the part, the feed processing route using both lateral and radial simultaneous feed methods.

Second, the cnc turning machining line adopts the CNC turning process to finish the workpiece. The commonly used feed path mainly includes the feeding route of the profiled contour of the part, the feed path that needs the tool change in the processing, and the processing according to each processing surface. Accurate planning of the feed path, in addition to the cutting process, but also pay attention to the tool cutting, cutting out and the cutting point position selection.

1. When designing the feeding route of the contoured part of the part, try not to arrange cutting, cutting, tool change and pause in the continuous contour trajectory so as to avoid elastic deformation and surface scratches on the workpiece.

2. If the tool change must be performed during the processing of the workpiece, the design of the feed path is mainly based on the requirements of the work order to determine the order of the machining tools and how each tool feeds the feed path. Connected.

3, the accuracy requirements of the workpiece surface are also related to the design of the feed route. If the accuracy requirements of the machining parts of the parts are not too different, the highest surface accuracy requirements shall prevail, and all the machining parts of the parts shall be completed by one continuous pass. If the precision requirements of the machining parts of the parts differ greatly, then the machining surfaces with close precision should be arranged within the same tool path to complete the cutting of the machining parts.
