NEW MANUAL FOR TESTING MACHINABILITY AIMS TO IMPROVE EFFICIENCY: Design engineers can use the method to select machining parameters for their cast parts

摘要

The machinability of a casting is influenced by the metal. Metallurgists and quality assurance managers wish to use machinability testing methodology to measure and record the effect of alloy type, metal alloy grade, composition, microstructure, mechanical properties and/or physical properties on enhancing machinability. Michael Finn, Finn Metalworking and Cutting Solutions, with support from the American Foundry Society (AFS), developed a manual for using factorial designed experiments to reduce the number of metalcasting experimental runs and identify the processing conditions affecting the machinability values.
