Abstract

 The wire electrical discharge machining
(WEDM) is widely used in the cutting of Bulk Continuous Filament (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 (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.
