With the development of chips, the development of automation technology is very rapid, especially in the aspect of numerical control automation, and the numerical control technology level represents the modernization level of national industry. In this era of labor shortage today, personnel costs are constantly rising and traditional labor-intensive industries must upgrade or be phased out. In modern manufacturing systems, numerical control technology is the key and is the basis for realizing automation, networking, flexibility and integration in manufacturing industry. In industrial production, gantry machines are often used. The gantry machine tool is an automatic machine tool with a program control system. The control system is capable of logically processing and decoding a program defined by a control code or other symbolic instructions, represented by coded numbers, which are input to the numerical control device via the information carrier. After operation, the numerical control device sends out various control signals to control the action of the machine tool, and the parts are automatically machined according to the shape and the size required by the drawing. The gantry machine tool well solves the problem of machining of complex, precise, small-batch and multi-variety parts, is a flexible and high-efficiency automatic machine tool, represents the development direction of modern machine tool control technology, and is a typical mechanical and electrical integration product. In the process of machining a product by using a gantry machine tool, auxiliary time such as workpiece loading and unloading, tool adjustment and the like, such as the coordinate of a part such as a corner of a workpiece, which is often required to be aligned in machining of the gantry machine tool, accounts for a considerable proportion of a machining cycle. At present, gantry machine tools in various types are available in the market, and gantry machine tools of different specifications and models adopt different tool setting modes under different conditions, and generally adopt a tool setting device, an edge searching device and a trial cutting tool setting method. When a tool or an edge finder with high machining precision requirement of the gantry machine tool is used, accurate tool setting operation is needed, the tool setting process is generally finished by manually operating the tool setting edge finder through a hand wheel, and the specific process is approximately as follows: 1. mounting a tool to the spindle; 2. the tool is slowly moved to the tool setting device by rotating the hand wheel; 3. when a cutter touches the tool setting device, the tool setting device displays to indicate that the cutter is touched, a system records the current XYZ coordinate value as a reference, and then the position of the cutter can be determined.
