Conventional technology are also today the main technology used for production of parts in mechanical engineering industry. In every machine shop we can see turning machines, milling machines, drilling machines and others. These machines are generally controlled by computers. But the modern production lines and production companies use also innovative technology to make production more effective, faster, less expensive. With regards of mentioned factors is possible to use also rapid prototyping technology, which can help in product developing, prototype creating but also in short-run or middle series production. Rapid prototyping technology include different techniques for product creation, using different procedures leading to various outputs. The final product can be made from various materials and parts can be used for several applications.

“…The choice of EDM tolerance is important in machining the workpiece. If the tolerances are left outside the gap, it is called “positive machining tolerance.” If they are left inside the gap, it is called as “negative machining tolerance” (Figure 19; Chiu et al , 2004). Although, both approaches have distinctive advantages in EDM, in choosing negative tolerances the unmachined materials remain on the workpiece.…”

PurposeIn electrical discharge machining (EDM) process, the production of separate electrodes for rough, semi‐rough and finish machining of dies and moulds having complex surfaces, results in high cost and long lead‐time in manufacturing. The purpose of this paper is to describe the machining performance of electrodes formed by using copper wire bunches (WBs) positioned to conform the surface to be machined was experimentally and theoretically analyzed. In the study, the variations in the machining rate, electrode wear rate, relative wear and workpiece surface roughness were examined for various discharge current and pulse‐time settings.Design/methodology/approachCopper WBs positioned to conform the surface to be machined in electric discharge machining. The variations in the machining rate, electrode wear rate, relative wear and workpiece surface roughness were examined experimentally for various discharge current and pulse‐time settings. The WB electrodes (WBEs) are proven to be satisfactory as electrodes for roughing operations in electric discharge machining.FindingsThe increase in number of wires and pulse energy result in decrease of relative wear for each wire in the electrode. The increase in number of wires in electrodes causes increase in machining area and in machining time in WBE method. With the increase of discharge current and pulse time, the electrode wear rate and material removal values increase and machining time decreases. By using the mathematical models obtained from the result of the experiments, the electrode wear rate, material removal rate, relative wear and the set length of wires for the desired cavity profile can be calculated. The labor cost of electrode manufacturing in the WBE method is lower compared to conventional solid electrodes. The use of WBE method for rough machining decreases machining cost and time. The use of WBE method decreases both the number of the electrodes required and the delay in starting machining due to the preparation of electrode in EDM.Originality/valueThis paper introduces the benefits of using WBE in electric discharge machining; wear and material removal characteristics of WBEs are introduced; the surface roughness characteristics of surfaces produced by WBEs are examined experimentally; and the effect of number of wires used in WBEs given (experimental findings).

“…Currently, many additive manufacturing machines import data from a CAD model in the stereolithography (STL) data format that uses triangular facets. 18,19 The formats that are ideal for layered building may not be optimal for free space deposition, so research into data formats that can represent the model and tool paths for free space deposition in an optimum way is needed. For example, Jacob et al 18 suggested using formats that represent the part geometry utilizing a mathematically precise format using splines.…”
