When evaluating the porosity, it is found that the pores are concentrated in the feed and sprue system, which has a positive eff ect on the quality of the casting. 6. Manufacturing a tool-electrode using casting technology has shown that all the accuracy and roughness parameters of the TE are within the specifi ed tolerance and correspond to the original data of the drawing. 7. An experimental study is conducted of the process of electrical discharge machining of a profi le groove with a tool-electrode, which was manufactured by the method of investment casting using an investment pattern obtained using rapid prototyping technology. It is found that the dimensions of the resulting groove meet the stated requirements. References 1. Su X., Wang G., Yu J., Jiang F., Li J., Rong Y.
