This paper shows the process of collecting and analysis of strain data during the internal machining process of an electrical motor casing. Eighteen motor cases were used to evaluate the strain at a critical point. Longitudinal and circumferential data were collected during those tests. Strain data were acquired using a multi-function data acquisition board and a HBM bridge. Tests were conduct upon request of the manufacturer in order to gain some insight, regarding strains, during the cutting process.
Some discussion is presented related to the strain data fluctuation during the cutting process.
