Selective laser melting technological process energy consumption prediction and energy-saving control method

Abstract

Disclosed is a selective laser melting technological process energy consumption prediction and energy-saving control method. The selective laser melting technological process energy consumption prediction and energy-saving control method comprises the steps that firstly, the power of all energy consumption parts of selective laser melting equipment is obtained, and power vectors of the equipment parts are obtained; then the time of all selective laser melting sub-technological processes is obtained, and time vectors of the sub-technological processes are obtained; then working states of the energy consumption parts of the selective laser melting equipment in all the sub-technological processes are obtained, and a working state matrix of the energy consumption parts and the sub-technological processes is obtained; energy consumption in the selective laser melting technological process, and energy consumption of the i energy consumption part and the j sub-technological process are calculated; and finally, energy consumption under different technological parameters and different part layout conditions is predicted based on an established energy consumption model, and the technological scheme with the minimum energy consumption is selected. The selective laser melting technological process energy consumption prediction and energy-saving control method is simple and easy tooperate, and by predicting the magnitude of energy consumption in the selective laser melting technological process, and the technological scheme with the minimum energy consumption is selected.

Description

technical field [0001] The invention belongs to the field of process control in the additive manufacturing process, and in particular relates to a selective laser melting process energy consumption prediction and energy-saving control method, which can predict the energy consumption of different process schemes, so as to select the scheme with the lowest energy consumption. Background technique [0002] As an emerging manufacturing technology, additive manufacturing, especially selective laser melting (Selective LaserMelting, SLM) process is being more and more widely used. However, due to the high power of the SLM process and the low production efficiency, it takes a lot of time to process parts and also requires a lot of energy. Therefore, it is urgent to study the energy consumption prediction method of the SLM process, and then reduce the energy consumption of the SLM process by selecting a reasonable process plan. [0003] SLM equipment has many energy consumption unit...
