ABSTRACT

The Electrical Discharge Machining (EDM) process is becoming increasingly used in the shipbuilding industry due to its suitability to produce complex geometries and the machining of materials with high mechanical properties. Although, it is necessary to deepen in its study to be able to adapt it to the own characteristics of the shipbuilding sector, mainly to the high volumes of material to eliminate that causes a strong degradation in the tools. This research focuses on the experimental study of surface contamination caused on the active surface of cutting tools in EDM processes due to material adhesion of machined parts during the process, being of interest in the manufacture of parts and components that require high manufacturing times. This work presents a series of findings that allow optimising the starting parameters of the process to increase the useful life of the tool and improve the surface finish of the manufactured parts.

摘要

电火花加工 (EDM) 工艺因其适用于生产复杂几何形状和加工具有高机械性能的材料而越来越多地用于造船行业。虽然，有必要深化其研究，以使其适应造船行业的自身特点，主要是为了消除导致工具严重退化的大量材料。本研究的重点是在电火花加工过程中由于加工零件的材料粘附而对切削刀具的活动表面造成的表面污染的实验研究，对制造需要高制造时间的零件和组件感兴趣。
