Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention.

[0017] The present invention can be applied to the turning processing method, aiming at the processing material which is difficult to break chips and is easy to generate with a long chip breaking length, it refers to changing the feed rate of the cutting tool to achieve the predetermined target starting from the chip breaking size. figure 1 The specific implementation process of the present invention is shown.

[0018] Step 1: Determine the material of the workpiece to be processed, and select the appropriate tool parameters according to the material.

[0019] Step 2: Determine the spindle speed, set the chip breaking length L and chip breaking thickness W, and select the initial pulse signal control function. Among them, the frequency of the pulse signal has a sinusoidal relationship with the time.

[0020] Step 3: According to the above conditions, write the CNC...

Abstract

The invention discloses a variable-feed turning chip breaking method capable of achieving real-time monitoring. The variable-feed turning chip breaking method is characterized in that when a numerical control machine tool carries out turning, the chip breaking thickness W and the chip breaking length L are taken as control targets, and a pulse control function is selected, so that the thicknesses of chips obtained after the cutting are inconsistent, the purpose of chip breaking is achieved, meanwhile, the cutting state is monitored in real time through an acoustic emission sensing module, if a certain section does not reach the predicted chip breaking state in the cutting process, the pulse control function is modified, it is ensured that chip breaking is completed, data of the whole process is recorded, an acoustic emission sensing technology and a variable feeding chip breaking method are utilized on a numerical control machine tool, no complex auxiliary device is needed, operation is easy and convenient, economical efficiency is good, and the automation degree is high.

Description

technical field [0001] The invention relates to the field of numerical control machining, in particular to an adaptive turning chip breaking method capable of real-time monitoring. Background technique [0002] With the continuous development of science and technology and social production, various fields have higher and higher requirements for the quality and automation of mechanical products. The application of CNC machine tools plays an important role in today's mechanical production field. In the process of CNC machining, the generation of chips will lead to hidden dangers such as insufficient machining accuracy, damage to workpieces, and injury to construction personnel. At present, the main methods of dealing with chips are: setting chip breakers in front of the tool, changing the shape of the main cutting edge, adding chip breakers, etc. However, the above methods have great limitations. Specific solutions are often required for different material parameters, and the...
