Abstract :  The wire electrical discharge machining insert ignore into journalissuearticles values(WEDM); is widely used in the cutting of Bulk Continuous Filament insert ignore into journalissuearticles values(BCF); spinneret molds. Because of the low surface roughness of the spinneret molds obtained by the WEDM method, it ensures that the polypropylene material has a steady flow, volume and cross-sectional shape. Since the yarn extruded from the sections on the BCF acquire a number of physical and visual properties surface roughness of these molds have a great of importance. In this context, a new model was developed to predict the surface quality of spinneret mold sections machined using WEDM by Analysis of variance. Machining parameters such as voltage, current, pulse time and wire feed rate were used as independent input variables and surface roughness was used as dependent output parameters.  Contribution of input variables into the output variable determined by means of analysis of variance insert ignore into journalissuearticles values(ANOVA);. Developed mathematical model estimations have been found to be in good agreement with the measured ones. The parameters with the most effect on surface roughness are listed as voltage, current, pulse, and feed, respectively.
