Embodiment Construction

[0032] Embodiments of the present invention will be further described in conjunction with the accompanying drawings.

[0033] The present invention provides an in-situ dressing method for a cup-shaped arc grinding wheel based on a cradle-type five-axis CNC machine tool. The dressing method is to install the cup-shaped arc grinding wheel 5 to be trimmed and the dressing wheel 4-1 on the five-axis CNC machine tool , the composite movement of the tool shaft and the turntable 3 is controlled by the numerical control system, so that the cup-shaped arc grinding wheel 5 and the dressing wheel 4-1 are trimmed in the manner of grinding, and the inner circular surface and the outer circular surface of the cup-shaped arc grinding wheel 5 Trim separately.

[0034] Specifically, the dressing method of the present invention is based on a five-axis processing machine tool and a cylindrical SiC dressing wheel, such as image 3 As shown, the specific device structure includes a fixture, a con...

Abstract

The invention discloses an in-situ dressing method of a cup-shaped arc grinding wheel based on a cradle-type five-axis numerical control machine tool. The dressing method is used in ultra-precision grinding and aims to solve the problem that the current cup-shaped arc grinding wheel is not easy to dress. The dressing method includes: installing the dressing grinding wheel on the turntable of the CNC machine tool, installing the cup-shaped arc grinding wheel to be trimmed on the main shaft of the machine tool; Intermittent dressing and grinding of arcs and outer arcs; in-situ measurement of grinding wheels through calibrated laser displacement sensors. The dressing method of the present invention performs in-situ dressing on the cup-shaped arc grinding wheel of the cradle-type five-axis processing machine tool, which solves the problem that the cup-shaped arc grinding wheel is difficult to dress due to the easy interference of the arc, and the dressing method reduces the wear of the grinding wheel and the high precision of the workpiece The impact of requirements, reduce the number of compensation processing, achieve deterministic processing, and improve the processing efficiency and processing quality of the entire workpiece.

Description

technical field [0001] The invention belongs to the technical field of precision machining, and in particular relates to an in-situ dressing method of a cup-shaped arc grinding wheel based on a cradle-type five-axis numerical control machine tool. Background technique [0002] Hard and brittle materials have excellent properties such as high strength, high hardness, and high wear resistance, and are widely used in national defense and civilian fields such as optics and machinery. However, this type of material has high brittleness, low fracture toughness, and the elastic limit is very close to the strength limit. When the load on the material slightly exceeds the elastic limit, fracture damage will occur. Brittle materials are generally processed by grinding, and the grinding process includes rough grinding and fine grinding. The grinding of hard and brittle materials mainly uses diamond abrasive grinding wheels. The grinding wheel of CNC machine tools will cause high tempe...
