In the process of using machine tools to manufacture parts, it is impossible for a production enterprise to fully check the accuracy of the machine tool every time a part is processed. Parts, because the accuracy deviation of the machine tool cannot be found in time, the accuracy of the product processed by the machine tool exceeds the manufacturing accuracy requirements of the part, resulting in the out-of-tolerance scrapping of the product

Embodiment Construction
[0019] The present invention will be further described below in conjunction with embodiment.
[0020] figure 1 with figure 2 It is a machine tool linkage deviation early warning method of the present invention. The method is first based on a device, including a blank body (1) and reference sides (2)-(9), and the blank body (1) is a workpiece blank that needs to be processed by a CNC machine tool , is generally a cube, the main features are an upper plane (11) and a lower plane (10), and the blank body is fixed on a CNC machine tool or a fixture. The reference sides (2)-(9) are attached to the edge of the blank body, the angle between the reference sides (2), (3), (6), (7) and the upper plane (11) is 90o, the reference side (4) , (9) and the included angles between the reference sides (5), (8) and the upper plane (11) are 100o and 80o respectively. The reference sides (2)-(5) and the reference sides (6)-(9) are on the same plane in the height direction of the blank (1).

The invention discloses a multi-shaft linkage numerical control machine tool linkage precision error alarming method. The multi-shaft linkage numerical control machine tool linkage precision error alarming method is based on a simple device. The device comprises a blank body and reference sides including vertical sides and oblique sides. The edges of the blank body are provided with the reference sides including the vertical sides and the oblique sides, wherein the vertical sides are perpendicular to the upper surface and the lower surface of the blank body, and the oblique sides form a certain angle from the upper surface and the lower surface of the blank body. During application, a group of the reference sides are machined along the upper surface of the blank body through a tool and then detected and calibrated; after the blank body is turned over and clamped, the tool moves along the contour of the other group of the reference sides and can theoretically and necessarily coincide with the reference sides machined before the blank body is turned over, and if the tool does not coincide with the reference sides machined before the blank body is turned over, errors on the surface precision of a machine tool exist. The machine tool precision error alarming method is simple and reliable and can timely find out the precision errors of the machine tool and accurately determine whether the precision of the machine tool can help machine qualified products for users and technologists.
Description
technical field [0001] The invention relates to an early warning method for linkage deviation of a machine tool, in particular to an early warning method for linkage precision deviation of a numerically controlled multi-axis linkage processing machine tool. Background technique [0002] In modern industry, many structural parts have complex structures and high precision requirements, and multi-station processing is required in the manufacturing process. Therefore, high-precision multi-axis linkage CNC machining machines are widely used. In the application process of such a high-precision CNC multi-axis linkage machine tool, with the wear and aging of the machine tool components, and the abnormal impact during use, the accuracy of the machine tool gradually decreases and becomes unstable. In the process of using machine tools to manufacture parts, it is impossible for a production company to check the accuracy of the machine tool for each part. Therefore, when the production ...
