Is Cutting Abrasive Waterjet a Solid or a Liquid?

conference paper

English

A model based at a shock waves theory requires cutting process presence in cutting kerf. Super-fast dynamical removal phenomena initiate an echo at an interface jet/erosion front consequently. The arrangement of the experiments was aimed to catch of these phenomena. Cutting flow of Abrasive Waterjet (AWJ) process at the interface - final workpiece margin /free space - faces to a nose creation. The nose is accompanied by overshooting phenomenon. An special test specimen is designed for cutting/machining ability of AWJ processes. It provides job-shop tests according the requirements to quick, cheap, exact and repeatable operative proofs. The test is founded at nose measurement. It serves to fast and exact evaluation of cutting process efficiency. It is a source of new economic savings and contribution of GACR Project 101/00/0890.
