Electrodischarge micromachining (EDMM) with universal electrode tool is the machining method, where the workpiece is being shaped by the replication of the working electrode path in workpiece material. EDMM process is mainly used for manufacturing prototype microparts and tools for microforming (ie. tools for microcasting, microforming, micro deep drawing, microembosing, micropunching or microextrusions) where the high precision is required. However during EDMM, due to electrode tool wear, some problems with optimal accuracy and surface quality occur. To minimalize the influence of electrode wear on shape and dimensional accuracy various tool wear compensation algorithms are used to correct the electrode movements. In the paper three most commonly used compensation methods were shortly described: Uniform Wear Method (UWM), Anticipated Wear Compensation (AWC) and Real Time Compensation Method. The main aim of this work was to determinate the influence of process parameters on material removal rate as well as on working electrode wear during EDMM. The accuracy of machining process was defined and at the same time the problem of working electrode wear compensation with Real-Time Wear Sensing method was undertaken.
