specific Embodiment approach 1

[0028] Specific implementation mode 1: A kind of ball-end grinding wheel precision dressing method based on double-arc fitting error compensation in this implementation mode is specifically carried out according to the following steps:

[0029] Step 1. Set the direction parallel to the axis of rotation of the main shaft of the machine tool as the z-axis, and the axis perpendicular to the z-axis on the horizontal plane of the machine tool as the x-axis, thereby establishing a coordinate system xyz; install the dressing wheel and the laser micrometer on the x-axis of the machine tool On the axis, the rotation axis of the dressing wheel is parallel to the y-axis of the machine tool, and the laser beam of the laser micrometer is parallel to the z-axis of the machine tool; the ball-end grinding wheel is installed on the z-axis, and the rotation axis of the ball-end grinding wheel is parallel to the z-axis; among them, The x linear axis and the z linear axis can be linked to realize ...

specific Embodiment approach 2

[0038] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the dressing wheel in Step 1 is a disc-shaped electroplated diamond grinding wheel, and the particle size can be 90-300 μm. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0039] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the ball-end grinding wheel described in Step 1 is a resin-bonded diamond grinding wheel with a particle size of 1-60 μm. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention relates to ball end grinding wheel precision dressing methods, in particular to a ball end grinding wheel precision dressing method based on bi-arc fitting error compensation. In order to solve the problems that the ball end grinding wheel dressing cost is high and the high surface precision and dimensional precision cannot be achieved easily, the ball end grinding wheel precision dressing method based on bi-arc fitting error compensation is provided. According to the method, on the basis of the characteristic that a disc-shaped electroplated diamond dressing wheel is low in abrasion loss, the dressing track is set so that in-place dressing of a ball end grinding wheel can be realized, the surface-shape error direction and magnitude are obtained through detection of the surface-shape contour of the primarily-dressed ball end grinding wheel and bi-arc fitting, error compensation is carried out at the precision dressing stage ultimately, and accordingly the ball end grinding wheel with the standard spherical face obtained on the surface and the target radius being r can be dressed. The ball end grinding wheel precision dressing method based on bi-arc fitting error compensation is applied to the field of ball end grinding wheel precision dressing.

Description

technical field [0001] The invention relates to grinding wheel dressing, error judgment and compensation methods, in particular to a ball-head grinding wheel precision dressing method based on double-arc fitting error compensation. Background technique [0002] Diamond grinding wheel has the characteristics of high grinding efficiency, good processing quality and long service life, and is an ideal processing tool for hard and brittle materials. Among them, the diamond ball head grinding wheel has a small size and a large grinding area, especially suitable for grinding steep aspheric inner surfaces and complex free-form surfaces, and is widely used in optics, aerospace and other fields. In the process of grinding with diamond ball-end grinding wheel, the surface accuracy of the ball-end grinding wheel will directly affect the surface accuracy of the workpiece, so it must be finely dressed in situ before grinding. There are many methods for dressing diamond ball head grinding...
