Study of surface topography created by abrasive waterjet cutting

Abrasive waterjet is one of the most rapidly improving technological methods of cutting materials. AWJ represents cold precise, computer controlled shape cutting without any strain. These attributes pose this technology to the position of permanent use in the future, which is the excellent outlook for expansion in large-volume sectors, especially where the materials with excellent utility properties are used. AWJ is owing to present high requirements for quality and productivity applied in full-automated workplaces with automatic CNC control. Such a way of controlling and surface measurement represents a possibility of optimising the production and quality control of AWJ technology. Knowledge of the surface quality and their classification is very important for machining techniques. While AWJ technology has already been solved using hardware and software (except for some specific cases), a way of measurements the quality of created surfaces has remained a serious technical problem. Measurement of surfaces generated by water jets and abrasive water jets is quite difficult. It is caused by specific surface structure because in contrast to classical methods, the surface created by AWJ is diffuse. In the monograph the optical methods is used for the investigation of the surface structure cutting of areas with the aim to propose the surface geometric parameters for advanced quality control of AWJ cutting process.
