Title

Hydroabrasive Cutting Head-Energy Transfer Efficiency

Abstract

The ability of an abrasive waterjet to cut materials traditionally considered difficult to machine is unmatched by alternative mechanical or thermal cutting techniques - the problems of material delamination and thermal deformation along the cutting path being eliminated. The effectiveness of hydroabrasive jets in such cutting applications depends on the energy which can be imparted to the abrasive particles. Many existing cutting head designs are based on the concept of entraining the abrasive grains in either single or multiple water jets within the head. Both the abrasive particle milling effect and the transfer of energy that take place between the water nozzle exit and the slurry nozzle inlet are introduced as criteria that can be applied in the evaluation of the effectiveness of the hydroabrasive cutting head design. This paper presents the results and general conclusions drawn from a test program designed to investigate both of these effects.
