Cutting plate is a difficult and time consuming task, especially when the job calls for a tight tolerance or an unusual shape. In those cases, can choose abrasive waterjet cutting. Abrasive waterjet cutting is an attractive process with many advantages. For efficient application abrasive waterjet cutting it is necessarily to define cutting data, especially cutting speed. High levels of contour precision at precisely defined cutting speed have an important effect on the quality of the cut. This paper gives results of the research referring to the determination of principal parameters by abrasive waterjet cutting. Cutting with waterjet costs less than traditional machining or other cutting methods. Waterjet is now the most cost effective method to cut steels. The cost ranges provide a basis for an cost estimation prior to plan of buying order of waterjet machine. The cost analysis of abrasive waterjet cutting is also presented in this paper.
