Comprehensive machining method for multiple products

Abstract

The invention belongs to the technical field of machinery machining and relates to a comprehensive machining method for multiple products. The comprehensive machining method for the multiple productscomprises the steps of designing the multiple products which are similar in machining height on a drawing which is as big as a raw material plate at the same time; fixing the raw material plate on a machining table of a CNC machine tool, then machining the raw material plate into the products on the drawing according to the drawing but leaving a bottom surface of the raw material plate that all the products are connected together, and obtaining CNC machined parts; and taking the CNC machined parts down by workers, then breaking the bottom surface according to contours of the products, and obtaining the products. According to the method, the multiple products which are similar in height are gathered on the same drawing for machining, so that the materials of the raw material plate can be used more reasonably, the continuous machining time can be long, the manpower can be saved and the activation can be obviously improved on the basis of not increasing equipment investment.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a time-saving and labor-saving multi-product comprehensive machining method. Background technique [0002] Many metal parts are machined using CNC machines. Compared with ordinary machine tools, CNC machine tools have many advantages such as high processing accuracy, stable processing quality, wide applicability, fast adjustment, high production efficiency, and labor-saving labor intensity. All kinds of products can be completed under the same CNC machine tool. When a factory wants to produce many kinds of parts, the general method is to design one kind of part on one drawing, then let the CNC machine tool process this type of product according to this drawing, and then design another kind of part on another drawing On the other hand, process the second type of products according to the second drawing, and so on. There are following problems in such processing: ...

AI Technical Summary

Problems solved by technology

[0003] ① The purchased raw material boards have fixed specifications. In order to reduce the waste of raw material boards, the raw material boards are often pre-cut into processing boards of a certain size, which increases the cutting time and labor.

[0004] ②The processing fixtures on CNC machine tools often use suction devices. The size of the processing plate will require workers to adjust the size of the suction area on the CNC machine tool. The actual adjustment process is quite cumbersome and takes up the use time of the machine tool.

[0005] ③If the processing volume of each product is not large, the CNC machine tool will stop frequently, requiring workers to take care of it all the time

[0006] Affected by this, the utilization rate of CNC machine tools is often as low as 30% or less

This is a great waste of productivity for a high-precision device
