Abstract
The invention discloses a method for measuring chip deformation. The existing method for measuring the chip deformation only measures the shrinkage coefficient and has large measurement error. The method converts the deformation of the metal chip into the deformation of the pattern, draws the concentric circular pattern on the surface of the metal material, measures the size of the pattern on the chip to calculate the shrinkage coefficient through cutting, and measures the curvature of the chip bending through a method of making an auxiliary line on the image, thereby achieving the effect of representing the chip deformation. The invention can systematically measure the longitudinal shrinkage coefficient, the transverse shrinkage coefficient and the bending curvature of the chip, and particularly provides a simple method for measuring the curvature radius of the chip, wherein the curvature radius can intuitively describe the bending degree of the chip.
Description
Technical Field
The invention belongs to the technical field of metal cutting, and particularly relates to a method for measuring chip deformation.
Background
The metal deformation is the fundamental problem in the metal cutting process, the cutting force and the cutting heat are caused by the deformation, and the shrinkage coefficient of the metal is an important parameter for representing the metal deformation. There are two methods for measuring the coefficient of metal shrinkage at present. The first is a gravimetric method, in which the relationship between mass and chip area and chip length is derived, and the area and length are inversely proportional to each other, i.e., the coefficient of contraction can be expressed as an area ratio, depending on the fact that the volume of the chip before and after being cut is constant. Since the mass and size of the chips are relatively small, the measurement requires a very high precision for the instrument, and therefore errors are unavoidable. The second method is simpler than the first method and uses direct measurement of the length before and after cutting to represent the shrinkage factor. However, both methods only measure the coefficient of contraction, and do not measure the curvature of the chip, and the second method only measures one longitudinal coefficient of contraction, which has large error and limited application range.
