Polar coordinate circular sawblade linear cutting method and linear cutting apparatus based on same

Abstract

The invention discloses a polar coordinate circular sawblade linear cutting method and a linear cutting apparatus based on the same. According to the cutting method, the linear cutting of a circular workpiece is realized by converting coordinate values of polar coordinates into programming codes; the linear cutting apparatus based on the polar coordinate circular sawblade linear cutting method comprises a wire conveying mechanism, a driving mechanism, a control system and a rotating mechanism. The polar coordinate circular sawblade linear cutting method has the beneficial effects that each fundamental figure of a cutting track is cut into n small sections; the polar coordinate values of a start point and an end point of each small section are solved; programming codes of each small section are generated; the actions of the rotating mechanism and a linear mechanism are controlled by the programming codes to realize cutting the workpiece; due to the application of the linear cutting method, secondary workpiece processing start point alignment is not needed, the processing of the circular workpiece can be completed in one step, and the radial jump precision is improved.

Description

technical field [0001] The invention relates to a polar coordinate circular saw blade wire cutting method and wire cutting equipment based thereon. Background technique [0002] In metal processing, when processing circular metal parts, especially circular metal sheets, wire electric discharge machining machines are often used to obtain circular saw blades. Circular saw blades are a general term for thin circular knives used to cut solid materials, such as diamond circular saw blades for stone cutting, high-speed steel circular saw blades for metal material cutting, solid wood, furniture, wood-based panels, aluminum Carbide saw blades for cutting alloys, etc. The current processing methods for the base of circular saw blades mainly include punch punching, laser cutting, and wire cutting. Among them, punch punching has been basically eliminated and is only used in some low-end chips. Laser cutting is now the main cutting method, but laser cutting The precision is not as hig...

AI Technical Summary

Problems solved by technology

[0004] 1) When cutting a circular workpiece by Cartesian coordinate line cutting, the cutting track will interfere with the supporting tooling of the workpiece, so secondary positioning is required. Generally, it is necessary to change the position of the supporting tooling to complete the cutting. It cannot be completed in one cut, which is time-consuming It is longer, which makes the operation process of wire cutting processing equipment cumbersome, low work efficiency, and small processing range;

[0005] 2) Traditional wire cutting requires secondary tooling, resulting in low processing accuracy;

[0006] 3) The processing range of ordinary machine tools is larger than the diameter of the workpiece, which increases the bed of the machine tool and increases the cost of the machine tool
