Verificación y comprobación de operaciones y parámetros de corte entre el torneado convencional y el torneado CNC : operación de cilindrado.

Abstract

In this work, 54 specimens were cylindered (27 on the manual turnstile TORRENT 42-72 and 27 on the CNC turnstile ROMI C420) with different combinations of cut parameters (spindle speed, feed rate, and depth of pass) in order to evaluate some criteria like amperage, machining time, error between final and expected diameter, roughness, taper and roundness. In order for realizing this work, transmission steel AISI 1018 was used as job material, and CNMG 12 04 08 – PM 4325 insert was used as job tool. In addition to some measure equipment like clamp meter used to evaluate the amperage of the machine, caliper to determine initial and final diameters (diameter error), roughness meter for the roughness and dial indicator for determining roundness and taper of the specimen. Once the data of the experimentation was obtained, a generalization of parameters to put in the machine (manual or CNC) to obtain the best condition of surface finish and geometric tolerance was realized. Finally, the results of the manual and CNC turnstile were compared with the objective to validate the actual conditions of the manual turnstile and determine if this is still optimum to mechanize specimens according to the requirements of any client.
