The article presents the basic parameters characterizing the abrasive water jet cutting, such as: water pressure (pw), cutting speed (vf), abrasive mass flow rate (ma) and the distance between forming nozzle and the cut material (l). Each of the mentioned parameters of the cutting process has been described in a separate subsection. The authors of the article focused primarily on the aspects related to the possibility of achieving maximum efficiency of the machining process while maintaining the assumed quality of cutting for individual cutting parameters. A detailed analysis of the topic was enabled the authors own research and an available literature on this subject. A closer understanding of the phenomena accompanying the abrasive waterjet cutting (AWJ) process and obtaining characteristics that would describe the influence of the tested output parameters in the function of input parameters will enable optimization of AWJ cutting process.

Abrasive Waterjet Cutting

Within a pulp industry production process, a drop in the performance of a wood log rotary debarker was identified. Such loss of performance was due to the occurrence of excessive wear of the device's cutting blades, requiring their regular and premature replacement. The material used to manufacture the cutting blades, Hardox 500, has characteristics considered adequate for the required use. However, it was concluded that the blade manufacturing process degraded its mechanical properties, leading to its premature wear when placed in service. The present study intends to propose, characterize, and validate an alternative cutting process to manufacture the debarker's cutting blades. Abrasive waterjet cutting technology was proposed to produce the cutting blades. The suitability of this manufacturing process is discussed considering the specified geometry and the material characteristics of the resulting cutting blades.

In this paper, a comprehensive experimental investigation on the surface roughness of metal kerf in abrasive waterjet cutting metal material is presented. Orthogonal experimental design method and analysis of variance are utilized in researching the effects of processing parameters on the roughness of smooth zone. By analyzing, it could be concluded that lower waterjet pressure, smaller cutting speed and abrasive grit, larger abrasive flow rate and appropriate standoff are favorable to generate smooth metal kerf. A verification experiment was conducted using an optimizing cutting condition. The result indicates that the surface roughness of metal kerf has been improved effectively.
