Which workpieces are processed by CNC machining centers?

March 11, 2022

The machining center machine is a high-efficiency automatic machine tool composed of mechanical equipment and numerical control system suitable for machining complex parts. CNC machining center is one of the most productive and widely used CNC machine tools in the world. Its comprehensive processing ability is strong. Once the workpiece is clamped once, it can complete more processing contents with higher processing precision. For batch workpieces with medium processing difficulty, its efficiency is 5 to 10 times that of ordinary equipment, especially it can be completed. The processing that cannot be completed by many common equipments is more applicable to single-piece processing with more complex shapes and high precision, or to multi-variety production with medium and small batch sizes.

CNC machining center machine feed processing route refers to turning tool from the knife (or machine fixed origin) from the start of the movement, until return to this point and the end of the processing program path, including cutting path and cutting tool, cut out, etc. Non-cutting, empty travel path.

The feed route for finishing is basically carried out along the outline of its parts. Therefore, the main focus of determining the feed route is to determine the feed route for roughing and empty travel.

In the processing of machining centers, the determination of processing routes generally follows the following principles.

1 It should be able to ensure the accuracy and surface roughness of the workpiece being machined.

2 Minimize the processing route, reduce idle travel time, and improve processing efficiency.

3 Simplify the workload of numerical calculation as much as possible to simplify the processing procedure.

4 For some re-used programs, subroutines should be used.
