Tribological Characteristics of Flat Surfaces of Parts made of Baked ПА-ЖГр2 Material after Needle Milling
Abstract
The paper considers regularities of machined surface formation and its wear resistance in the process of needle milling of baked ПА-ЖГр2 material. Roughness of the machined surface is reduced as feed and tightness are increased. The surface being machined does not practically have pores and traces of single needle trajectories and rolls of deformed metal along their lateral sides are observed. Instant and average friction coefficients for various machining conditions differ approximately by 10 %, difference in relative solid surface wear is greater by 3 and more fold in accordance with machining conditions. The minimal intensity of surface wear process after needle milling is observed while machining it with minimal milling speed and feed and maximal tightness.
