Automatic start-stop control method for chip removal system of numerical control machine tool

Abstract

The invention relates to an automatic start-stop control method for a chip removal system of a numerical control machine tool, and the numerical control machine tool comprises a main shaft, a main shaft operation timing system, a main shaft operation sensing system, a chip removal system and a chip removal timing system. The method comprises the following steps: 1), enabling the main shaft operation sensing system to sense whether the main shaft operates or not: executing step 2) if the main shaft operates, or else executing step 5); 2), starting the main shaft operation timing system to record the accumulative operation time duration delta(h1) of the main shaft, and executing step 3) if delta(h1) is equal to delta(H1); 3), turning off the main shaft operation timing system, carrying out the zero clearing of the delta(h1), starting the chip removal system to remove chips, synchronously starting the chip removal timing system to record the chip removal time duration delta(h2) of the chip removal system, and executing step 4) if delta(h2) is equal to delta(H2); 4), turning off the chip removal system, stopping the chip removal, synchronously turning off the chip removal timing system, carrying out the zero clearing of delta(h2), and repeatedly carrying out the step 1); 5), turning off the main shaft operation timing system, the chip removal system and the chip removal timing system.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to an automatic start-stop control method of a chip removal system of a numerical control machine tool. Background technique [0002] Saving resources is the basic national policy of our country, and it is also the fundamental requirement to improve the economic efficiency of enterprises and enhance the core competitiveness of enterprises.

Problems solved by technology

[0004] 1. The start and stop of the chip removal system need to be manually operated by the operator. If the operator forgets to press the start and stop button of the chip removal function, the chip removal system will not work, and the chip removal will not be possible, resulting in the accumulation of iron chips and affecting the performance of the machine tool. even damage the machine

[0005] 2. After pressing the start and stop button of the chip removal function, the chip removal system is always working. However, in the actual use of the machine tool, one workpiece needs to be replaced after another is processed. During this period, no iron chips will be generated. Some workpieces often need to be clamped for a long time. If this start-stop control method does not manually stop and close the chip removal system during this period, the chip removal system will not be automatically closed, which leads to energy waste.

[0006] 3. Even during the processing of the workpiece, chip removal is not always needed, and the chip removal system is always working, which also causes energy waste
