Multi-layer cutting bed and tool turning control method and system thereof

Abstract

The invention discloses a multi-layer cutting bed and a tool turning control method and system thereof. The tool turning control method comprises the following steps: calculating a compensation angletheta according to a formula, wherein K is a preset sensitivity coefficient of cutting bed cloth, r is the turning radius of a line segment to be cut, and L is the width of a tool; and when the tool moves to the starting end of a curve track, controlling a tool nose of the tool to deflect outwards in the radial direction of the turning radius of the line segment to be cut according to the compensation angle theta. By applying the method, the tool is controlled to deflect outwards in the radial direction through the compensation angle so as to compensate the cutting angle of the tool, stress ontwo sides of the tool is balanced, and the linear shape of the tool is restored; when curve cutting is carried out on the multi-layer cutting bed, consistency of cutting surfaces of an upper layer and a lower layer can be guaranteed, and cutting precision can be improved; the problem that the upper and lower layers of the material are inconsistent can be corrected only through compensation anglecompensation without arranging an additional sensor; and when it is detected that the turning radius of the line segment to be cut is smaller than a preset value, a tool compensation failure alarm isprovided, and a worker is reminded to conduct operation in time.

Description

technical field [0001] The present invention relates to the technical field of cutting on a cutting machine, and more specifically, relates to a method for controlling the turning of a multi-layer cutting machine tool, and also relates to a multi-layer cutting machine tool turning control system and a multi-layer cutting machine. Background technique [0002] The cutting system adopts the contact knife cutting method, and the cutting edge of the knife must be in close contact with the fabric before it can cut the fabric. The cutting knife is cut in the fabric that is compacted by the pressure difference caused by vacuuming. In this state, the cutting knife must not only move in the plane, but also rotate around the Z axis at the same time, but also at a fixed frequency. Do up and down reciprocating vibration, so the shape of the cutter will be greatly affected. Such as figure 1 as shown, figure 1 It is a schematic cross-sectional structure diagram of a cutter cutting clot...

Problems solved by technology

The closer to the bottom layer, the more serious the bending of the cutter body, causing the cutter to deviate from the design contour line, resulting in a large size error. If there are no improvement measures during processing, it will inevitably cause the top and bottom samples of the fabric to fail to maintain Consistent, resulting in a lot of waste, if not compensated, it may cause inconsistency between the upper and lower layers, resulting in cutting quality problems, causing material waste; or reducing the cutting thickness to improve cutting quality, which seriously affects production efficiency
