Abstract

The authors conduct designed experiments to ascertain the most efficient method of magnetic-

abrasive machining. Workpiece surface machining along and across the roughness marks at an

angle of 45° to the marks is investigated. In magnetic-abrasive machining of a workpiece the final

finish value will depend on the size of surface asperities before machining, on the direction of the

feed movement as well as on the processing time. An experimental setup was developed. Each

specimen was machined 4 times for 15 seconds. After each stage of processing, roughness was

measured on the profilograph-profilometer. The results obtained in the experiment are presented by

graphs. After the experiment it was concluded that magnetic-abrasive machining of workpieces

across roughness scratches is the most productive method in contrast to the longitudinal machining

under the same initial and processing conditions.
