The problems of pattern cutting as applied to flexible elastic mesh fabrics (lace) are described within the context of the total manufacturing process. While the design and knitting stages of lace manufacture are highly computerised, providing associ

In this article a fundamentally new approach to cutting patterned breadths of lace fabric from a mesh backing web is presented. A line scan camera-based vision system employing a special tracking algorithm is used to detect pattern registration of la

The cutting of patterned edges of lace fabric using a machine based purely on mechanical concepts has fundamental problems. This process imparts forces into the workpiece causing local deformation of the fabric which reduces the cut edge quality and

A vision directed CO2 laser cutting concept for separating a patterned material from a backing net web has been successfully achieved. The concept allows automatic processing of flexible materials at higher feed velocities with improved cut edge qual

The hardness and brittleness of high performance engineering ceramics such as zirconia, aluminia, silicon carbide and silicon nitride makes traditional processing very expensive and time consuming. Efforts have been made to cut thick commercial ceram
