Unattended machining method for numerical control machining equipment

Abstract

The invention provides an unattended machining method for numerical control machining equipment, which comprises the following steps of: before unattended machining, installing all parts in place, preparing a cutter of a machine tool, calling a numerical control program, and starting continuous production; monitoring the load condition in real time in the production process, and when the cutting load of a certain point of the part is larger than a threshold value, conducting shutdown; before part hole machining, measuring the length of a hole machining tool, and when the deviation between thelength of the tool and the tool length recorded by a system is larger than a set value, conducting shutdown; after part of the set part machining content is completed, using a measuring head in the machine tool for measuring the machining size concerned in the part, if the size exceeds a set value, conducting shutdown, and if the size is within the tolerance range but deviates from a median, conducting tool compensation, and ensuring the consistency of the machining size; and the process safety and the quality safety are guaranteed by monitoring the machining process, and if data monitoring inthe machining process is not abnormal, the machining program normally runs until machining is completed. The numerical control equipment is improved on the basis of existing numerical control equipment, and unattended machining of the numerical control equipment is achieved.

Description

technical field

[0001] The invention relates to the technical field of unmanned numerical control machining, in particular to an unattended machining method for numerical control machining equipment. Background technique

[0002] With the vigorous development of intelligent manufacturing, CNC machine tools are developing towards high speed, high efficiency and high precision, but the price of intelligent equipment or intelligent manufacturing production lines is often expensive. For most enterprises, unless they are used for the processing of specific products on specific occasions, otherwise Difficult to support investment in equipment or production lines.

[0003] Many processing units are limited to the problems of labor costs, small batches and many varieties of products, and the operating rate and effective running time of CNC equipment are often insufficient. Prolonging the effective running time of CNC equipment is the best way to increase production capacity without...
