A multi-layer cutting machine and its tool steering control method and system

Abstract

The invention discloses a multi-layer cutting machine and its tool turning control method and system, including calculating the compensation angle θ according to the formula, wherein, K is the preset sensitivity coefficient of the cutting bed material, r is the turning radius of the line segment to be cut, L is the width of the cutter; when the cutter moves to the beginning of the curved track, the tip of the cutter is controlled to deflect outward along the radial direction of the turning radius of the line segment to be cut according to the compensation angle θ. Applying this method, the radial outward deflection of the tool is controlled by the compensation angle to compensate the cutting angle of the tool, so that the force on both sides of the tool is balanced, and the straight shape of the tool is restored; when cutting a curve on a multi-layer cutting machine, it can ensure The cutting surface of the upper layer and the lower layer are consistent, which improves the cutting accuracy; it does not need to set additional sensors, and the problem of inconsistency between the upper and lower layers of the material can be corrected only by compensation angle compensation; when it is detected that the turning radius of the line segment to be cut is less than the preset value, the tool will There is no way to compensate for the alarm, in order to remind the staff to take action 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
