Curve cutting system of cutting bed

Abstract

The invention provides a curve cutting system of a cutting bed. The curve cutting system of the cutting bed comprises one locating point selection module, one locating point radius computation module,one maximum radius speed definition module, one minimum radius speed definition module and one cutting speed execution module. The cutting speed execution module is used for selecting a continuouslyvariable speed value in a range of a maximum cutting speed value and a minimum cutting speed value and cutting the cloth, and the continuously variable speed value follows an equation that V is equalto KRf+d, wherein V is corresponding speed when radius is R, and K, f and d are variables. The curve cutting system of the cutting bed has the advantages that various curve speed optimization schemescan be designed according to actual requirements and are converted into mathematical formulas, so that only an appropriate speed scheme needs to be selected when the cloth is cut, and further the aimof simplification is achieved; meanwhile, cutting can be carried out at different speeds according to curves with different radians, and the effect of optimization is achieved, so that cutting qualitycan be improved.

Description

technical field [0001] The invention relates to the field of garment machinery, in particular to a curve cutting system for a cutting bed. Background technique [0002] With the continuous update and development of the clothing industry and people's constant pursuit of clothing quality, cutting machines are more and more widely used in various fields of clothing. During the cutting process of the cutting bed, it cuts the original fabric according to the graphics designed by the CAD software to cut out high-quality pieces. As we all know, the coordinate system of the CAD is a Cartesian coordinate system, so each point of the outer contour of the piece to be cut can be positioned and represented by the Cartesian coordinate system, so that the cut can be The outer contour of the film is digitized to facilitate cutting on the CNC cutting machine. [0003] At present, with the continuous development of numerical control technology, it has had an important impact on many importa...
