Machine tool power consumption prediction system and method

Abstract

The invention provides a machine tool power consumption prediction system and a method. The machine tool power consumption prediction system configured for predicting power consumption of at least one machine tool. The machine tool being for executing numerical control programs to produce parts, and various parameters are included in each of the numerical control programs. The machine tool power consumption prediction system includes a power consumption database and a computer, the database stores power consumption data associated with different values of the parameters included in numerical control programs. The computer is configured to assess the numerical control program against the power consumption database and generates a power consumption estimate associated with each of the numerical control programs to be executed by the machine tool.

Description

technical field [0001] The present invention relates to a system and method for predicting power consumption of a machine tool, in particular to a system and method for predicting power consumption according to the processing program and processing parameters of the machine tool. Background technique [0002] Cost control is an important ability for enterprises to rely on for profit. In the processing industry, especially in the industry where machine tools are used to process workpieces, electricity expenditure accounts for an important part of the cost. In order to reduce the electricity expenditure, the factory will sign a long-term contract with the power supply manufacturer to obtain a lower unit electricity price. The content of the long-term contract stipulates the amount of electricity consumption and the unit electricity price. If the amount is exceeded, it is often necessary to bear a huge fine or pay a higher unit price. Obtain electricity that exceeds the electri...

Problems solved by technology

[0003] In order to avoid the cost advantages brought by the long-term contract from the extra expenses incurred by exceeding the quota, or the factory will spend excess power costs due to the high contract quota, many factories have introduced smart meters to record the overall power consumption of the factory, and use this The quota is set as a benchmark. However, although this method can control the total electricity, it will affect the production and manufacturing schedule of the factory. For example, the factory may have different monthly production volumes, making estimates inaccurate, or producing different The products have different power consumption, or the production must be increased to meet the needs of customers. The factory can only pay a fine, or purchase power generation equipment by itself to avoid being fined
