Process capable of improving machining quality of numerical control mold

Abstract

The invention discloses a process capable of improving the quality of mold numerical control machining, which obtains a constant cutting layer area and material removal rate through calculation, so that the cutting load and the tool wear rate are kept in balance; the inclined lower knife with an inclination angle of 20° to 30° is adopted Method; provide root cleaning to remove corners with large remaining machining allowance after rough machining to ensure uniform machining allowance in subsequent processes, and the contact point between the tool and the workpiece changes with the surface slope of the machined surface and the effective radius of the tool. , while defining the amount of side engagement, define the height of the remaining area of ​​the machining surface. The radius of curvature of the finishing surface should be greater than 1.5 times the tool radius. In the finishing machining of the mold, when cutting in and out of the workpiece, the The change of direction should adopt arc or curve transfer as far as possible. This process can not only improve the efficiency of mold processing, but also ensure the processing quality, and the molding quality is higher when the subsequent mold is used.

Description

technical field [0001] The invention relates to a technology, in particular to a technology capable of improving the quality of mold numerical control processing. Background technique [0002] Numerical control is the abbreviation of digital control, and numerical control technology is a method to control mechanical movement and processing process by using digital information. The early numerical control system was composed of hardware circuits called hardware numerical control (Hard NC). After the 1970s, hardware circuit components were gradually replaced by special computers and called computer numerical control systems. Generally, special computers were used and equipped with interface circuits. It can realize the control of multiple CNC equipment actions. Therefore, the current numerical control is generally CNC (computer numerical control), and the concept of NC is rarely used anymore. CNC lathe feed processing route refers to the path that the turning tool moves from...
