Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] In an embodiment of the present invention, a CNC processing method includes the following methods:

[0020] (1) Focus on the tool brand. Among the many tool brands, select the tool that is suitable for the type of steel you are processing. During the process of processing different steel materials, you must test the wear value of the tool before and after processing and make a record. The wear value is measured by time, one hour, two hours, three hours ...

Abstract

The invention discloses a CNC machining technological method. The CNC machining technological method comprises the following steps: (1) selecting a tool suitable for self-machining steel types, and testing and recording attrition values, before and after machining, of the tool in a process of machining different kinds of steel; (2) testing tool attrition data values, selecting a finish machining tool to firstly fine machine part features after machining in rough machining is completed, reserving 0.2-mm steel at periphery for being not machined, carrying out canonical data finish machining after parts are integrally machined, wherein high-quality tool meets a +/-0.02mm machining tolerance range; and (3) dividing a CNC milling mode into a down milling mode and an up milling mode, wherein surface roughness of up milling machining is superior to that of down milling machining. The machining technological method disclosed by the invention can be widely applied to various machining fields, can improve efficiency of machinery within short time according to conditions of factor equipment, further can improve machining quality, can shorten the machining period, and can reduce the production cost.

Description

technical field [0001] The invention relates to the technical field of numerical control machinery, in particular to a CNC processing method. Background technique [0002] CNC (Numerical Control Machine Tool) is the abbreviation of Computer numerical control machine tool (Computer numerical control), which is an automatic machine tool controlled by a program. The control system can logically process the program specified by the control code or other symbolic instructions, and decode it through the computer, so that the machine tool can perform the specified action, and the blank can be processed into a semi-finished product part through tool cutting. [0003] At present, the most widely used CNC machining machinery in the global mold industry, but whether it is imported precision or domestic CNC CNC machinery, after the mold parts are processed, the surface finish and roughness cannot meet the requirements of precision parts, especially large mold parts. , After CNC machini...
