Изготовление сложнопрофильных электродов-инструментов с применением технологии быстрого прототипирования

technological capabilities of manufacturing complex-electrode-tool (ET). In traditional manufacturing of complex electrode-tool, its model is divided into elementary sections and each section is manufactured separately and subsequently assembled to form a tool. The resulting composite electrodes do not allow processing parts with high precision. The cost of manufacturing the composite electrode depends on the complexity of the work profile and often the creation of advanced components such electrode becomes economically advantageous. Purpose to investigate the possibility of the use of rapid prototyping technology to create complex electrodes. An experiment to create complex-tool-electrode in the form of mobile phone panel with the use of SLA technology for investment casting. To create a 3D model used reverse engineering principle with the use of a coordinate Contura Carl Zeiss G2 measuring machine. Growing master electrode model was conducted on the mask Installation type Envisiontec Perfactory XEDE. On the basis of the master model formed by the model kit for the implementation of the technology of casting, investment casting. Deviation from the workpiece dimensions of ET dimensions not exceeding 20%. The treatment process was accompanied by stable without causing sparking circuit. By increasing the depth of processing, due to the deteriorating conditions washout erosion products (sludge), the performance of EDM process decreased. The highest concentration of the slurry was observed on the concave surface of the electrode. Analysis of economic efficiency of application of rapid prototyping and casting techniques, investment casting to create an electrode-tool selected items showed a decline in the economic costs of 35%. Cost reduction is achieved by the absence in the manufacturing process of the electrode-tool blade expensive small-sized tools and tooling. The use of reverse engineering techniques, together with the rapid prototyping and casting, investment casting can reduce the time to prepare EDM technology.
