  • What principle should be followed in the arrangement of machining sequence of CNC machining center?

    The arrangement of the processing sequence should be considered according to the structure of the parts and blank condition, as well as the need for positioning clamping, focusing on the rigidity of the workpiece is not destroyed. The order should generally follow the following principles:

    (1) The processing of the previous procedure shall not affect the positioning and clamping of the next procedure. The processing procedure of universal machine tool interspersed between them shall also be considered comprehensively.

    (2) Advance the machining sequence of the inner cavity, and then carry out the contour machining process.

    (3) It is best to connect with the same positioning, clamping method or the same knife processing process, in order to reduce the number of repeated positioning, the number of tool change and the number of moving plate.

    (4) In the same installation of multiple processes, should be arranged first to the workpiece rigid damage small process.

  • How to divide the process?

    The division of NC machining procedures can generally be carried out according to the following methods:

    (1) The tool sequence method is to divide the process according to the tool used, and finish all the parts that can be completed with the same tool. With a second knife and a third to do whatever else they can. This can reduce the number of tool change, compress the space time, reduce unnecessary positioning error.

    (2) For processing parts of the processing content of a lot of parts, according to the structural characteristics of the processing part into several parts, such as internal shape, shape, surface or plane. Generally first processing plane, positioning surface, after processing holes; First processing simple geometric shapes, then processing complex geometric shapes; First machining parts with low precision, and then machining parts with higher precision requirements.

    (3) For parts prone to processing deformation with rough and finish processing, due to deformation that may occur after rough processing and need to be calibrated, so generally speaking, where rough and finish processing should be separated.

    To sum up, in the division of the process, we must depend on the structure and technology of the parts, the function of the CNC machining center, the number of parts CNC processing content, the number of installation times and the flexible grasp of the production organization of the unit. It is also suggested that the principle of process concentration or the principle of process dispersion should be determined according to the actual situation, but it must strive to be reasonable.

  • In CNC machining center workpiece clamping way to determine the several aspects should pay attention to?

    The following three points should be paid attention to when determining the positioning datums and clamping schemes:

    (1) Strive to design, process, and programming calculation of the benchmark unity.

    (2) As far as possible to reduce the number of clamping, as far as possible after a positioning can be processed out of all the surface to be processed.

    3) Avoid using manual adjustment schemes.

    (4) The fixture should be open, its positioning, clamping mechanism can not affect the processing of the knife (such as collision), encounter this kind of situation, can be used with a vice or add the bottom plate to pull the screw clamping way.
