Embodiment

[0083] Embodiment: On a CK6136H CNC lathe, the machine tool energy-saving operation method provided by the present invention is adopted. The part processed by the machine tool is a pallet, wherein the machine tool mainly completes drilling, rough / finish turning of the end face of the pallet and rough / finish turning holes during processing. The device for measuring machine tool power is HIOKI3390 power analyzer.

[0084] (1) Acquisition of basic parameters:

[0085] The basic parameters of the machine tool running state configured by the parameter configuration module are shown in Table 3 and Table 4. The time parameter of the processing interval is: the average processing interval of the machine tool is 24s; since the exponential distribution can be used to represent the time interval of independent random events, the index The reciprocal of the parameter λ in the distribution represents the expectation (average interval time) of the time interval of independent random events,...

Abstract

The invention provides a machine tool energy-saving running method for switching machine tool states within a random machining interval. Firstly, a machine tool energy-saving running strategy is made according to the randomness of the machine tool machining interval; then, based on an established machine tool machining interval energy-consuming model, power of the running states and other basic parameters, running parameters in the made energy-saving running strategy are optimized; finally, according to the energy-saving strategy and the optimized running parameters, a machine tool energy-saving running scheme, namely the running state track of a machine tool within the machining interval, is acquired, and support is provided for saving energy of the machine tool within the machining interval. The method solves the problem how to make a machine tool energy-saving running method within the random machine tool machining interval caused when a workpiece reaches randomly and the problem of improving the energy utilizing rate within the random machining interval of the machine tool.

Description

technical field [0001] The invention relates to the fields of energy consumption in machinery manufacturing, numerically controlled machine tools, and the like, and in particular to a machine tool energy-saving operation method for switching machine tool states within random processing intervals. Background technique [0002] my country is a big manufacturing country with about 8 million machine tools. If the average rated power of each machine tool is 10kW, the total power is about 80 million kilowatts, which is more than three times the total installed capacity of the Three Gorges Power Station of 22.5 million kilowatts. The amount is amazing. At the same time, a large number of statistical surveys show that the energy utilization rate of machine tools is very low on average, less than 30% on average. Therefore, it is of great significance to improve the energy utilization efficiency of machine tools and explore feasible energy-saving methods for machine tools. [0003] A...
