Problems solved by technology

At present, circular saws are used to process curved surfaces using the method of circular saws maintaining horizontal and straight cutting. The advantage of this processing method is that it can process small curved stones with large curvatures without being limited by the curvature. Step-type undercut occurs, resulting in excessive roughness of the machined surface

Embodiment Construction

[0021] The present invention will be further described below through specific embodiments.

[0022] The invention discloses a method for cutting a vertical curve with a circular saw and preventing overcutting, in particular a method for cutting a vertical curve with a small curvature and preventing overcutting with a circular saw, specifically comprising the following steps:

[0023] Step 1. Obtain the target vertical curve information to be processed from the DXF file, and the vertical curve is a vertical curve in the form of a polyline. Obtain the vertical curve information in the form of a polyline from the DXF file, including the point coordinates P on the vertical curve i (x i ,y i ,z i ) and the normal of the vertical curve n(x n ,y n ,z n ).

[0024] Step 2. Calculate the bias direction vector.

[0025] If you use a circular saw to cut the vertical curve directly according to the vertical curve information obtained in step 1, the following will appear: figure 1...

Abstract

The invention relates to a method for cutting a vertical curve through a disc saw and preventing overcut in stone processing. According to polyline-form vertical curve information obtained from a DXFfile, an offset direction vector is calculated; overcut-preventing offset calculation is conducted according to the direction vector; and simulating processing and actual processing are conducted through a method without overcut-preventing offset treatment and an overcut-preventing offset treatment method correspondingly, and the comparison result of simulating processing and actual processing verifies the fact that through the method, the vertical curve can be cut, and overcut preventing can be achieved.

Description

technical field [0001] The invention relates to stone processing, in particular to a method for cutting vertical curves with a circular saw and preventing overcutting. Background technique [0002] Longitudinal cutting is done on the wavy surface, and the longitudinal curve obtained on the longitudinal section is a vertical curve. Vertical curves are widely used in road and railway design, and the present invention extends it to stone processing. At present, circular saws are used to process curved surfaces using the method of circular saws maintaining horizontal and straight cutting. The advantage of this processing method is that it can process small curved stones with large curvatures without being limited by the curvature. Step-type undercuts appear, resulting in excessive roughness of the machined surface. In order to solve the above problems and combine the characteristics of circular saws with circular outer contours, for processing large curved stones with small cur...
