Abstract
Abstract High pressure abrasive water jets (HPAWJ) are an emergent excavation technology. Despite being used for several applications since the nineteenth century, it is only in recent decades that this excavation purpose has been considered. This is the result of evolution in high pressure pump technology and parameter investigation. Special highlight should be given to optimization works which improve knowledge about the main parameters. However, studies usually neglect the importance of HPAWJ cutting strategies, and only consider bidimensional approaches as options for nozzle movement. This article analyzes and proposes an operational cycle based on a tridimensional approach for HPAWJ. Higher removal rates and lower energetic consumption are expected in comparison with traditional strategies.

Summary
The considerable amount of power improving the advance rate and cutter carried by high pressure abrasive water lifetime. Similar results were found by jets (HPAWJ) has made possible their use Ciccu and Grosso (2010). They affirm in most areas of modern industry, that water jet assistance is effective in including the automotive and aerospace improving the performance of mechaniindustries, construction engineering, cal tools. One of the most challenging Kouzmich and Merzlyakov (1983), Fenn uses is related to oil drilling and mining et al (1985), and Ciccu and Grosso technology which, due to the great vari- (2014). A different approach has been followed by Lu et al (2013) They proposed a drilling machine for coal mining that digs the rock in two stages, one with a water jet and another with mechanical enlargement
