3 point you must to know for design complex CNC Machined Parts

Complex parts are the most common processing products in CNC machining.In the process of processing complex parts,Its processing route will be covered.
Including selection processing methods, division of processing stage, division process, processing sequence arrangement and determination of the processing route and so on.

1.Determination of parts blank

According to the parts process design, the selection of the blank is to determine the type of the blank, the manufacturing method and the size of the blank after determining the residual amount.

The material is steel. According to technical requirements,The parts are required to be deburred,that is to ask for the appearance of clean and beautiful.According to the structural shape of the parts overall dimensions,can select forging.

It is necessary to select the steel that has been processed, because it has a high hardness and is suitable for cutting.

2.Determination of locating datum of complex parts

When selecting coarse benchmarks for processing, the key consideration is how to ensure that there is sufficient allowance for each machining surface.Make the size and the position of machined surface and unmachined surface meet to prints.Therefore, the rough datum selects the blank plane.According to the processing of the concave, the machining requirements of the hole,select the base plate to location datum.

3.Machine selection

Different types of parts should be machined on different CNC machines,by different CNC machining process, and machine tools should be selected according to the design of the parts.

1) The CNC lathe is suitable for machining complex shaft parts and the mold inner cavity formed by the rotating complex curve.

2) CNC vertical machining center are suitable for processing box, box cover, flat CAM, shape complex plane or the internal and external cavity of the mould.

3) The CNC horizontal machining center is suitable for processing all kinds of complicated box parts, pump body, body, shell and so on.Multi - coordinate horizontal machining center can also be used to process various complex curves, surfaces, impeller, mould and so on.
