Embodiment Construction

[0052] The present invention will now be explained in detail in conjunction with the embodiments and the accompanying drawings.

[0053] The control method of material cutting power and energy consumption in the variable cutting rate process of the embodiment of the present invention comprises the following steps:

[0054] Step 1. Obtain the value combination of cutting elements. For each combination of values, perform idle cutting and collect the power of idle cutting of the machine tool in real time, and then perform cutting according to the same combination of cutting elements. The combination of values The corresponding variable cutting rate process is divided into several sub-intervals with equal time intervals, and the cutting power of the machine tool in each sub-interval is collected in real time.

[0055] The embodiment of the present invention takes the end face process as an example, and the value combinations of different cutting elements are shown in Table 1.

Abstract

The invention discloses a material cutting power and energy consumption obtaining and energy-saving control method in a variable cutting rate process. The method includes the steps that 1, value combinations of cutting elements are obtained, and the empty feeding power and cutting power of a machine tool are collected in real time for each value combination; 2, the material cutting power of a subsection is obtained according to the empty feeding power and the cutting power of the subsection; 3, the material cutting power and the value of the corresponding cutting element are put into an average cutting power computational formula of the subsection, and fitting is carried out; 4, the material cutting power and energy consumption computational formula of the variable cutting rate process is obtained according to functions of the cutting elements relative to time; 5, the material cutting power peak value and the energy consumption value of the variable cutting rate process are obtained after calculation, and the optimal variable cutting rate process is selected for cutting. According to the method, operation is easy, accuracy of predicting the power and energy consumption is high, and the method can be conveniently popularized to combination of machine tools, work piece materials and tools of other types.

Description

technical field [0001] The invention relates to the technical field of energy consumption forecasting in machining processes, in particular to a method for obtaining and energy-saving control of material cutting power and energy consumption in a variable cutting rate process. Background technique [0002] Manufacturing has become one of the main sources of energy consumption and carbon emissions today, and the issue of energy conservation and emission reduction in manufacturing has attracted widespread attention from governments, enterprises, and university research organizations. As a main processing method in the manufacturing industry, mechanical processing technology occupies a large proportion in the overall energy consumption of the manufacturing industry. Therefore, it is urgent to model the energy consumption of the machining process, lay the foundation for the energy optimization and energy saving of the machining process, and further promote the energy saving and e...
