A Study on the Flatness Measurement Device for Engine Covers of Automobiles

The purpose of this study is to develop a method to measure the flatness of automobile engine covers in order to ensure quality and prevent defects in sites where manual quality control is in place. The automobile engine cover is manufactured with aluminum using the deep drawing method. There can be an oil leak when there is a crack in the pressurized parts during processing or due to poor flatness at the joints when the cover is mounted on the engine. Therefore, flatness is one of the most important quality inspection items for engine covers. In this study, the researchers developed an instrument to measure the flatness of automobile engine covers in order to ensure quality and prevent defects in sites where manual quality control is in place. This shortened measurement time contributed to the enhancement of productivity greatly. If there is a defect, it was shown as in Figure 8. In order to detect defects, the resultant values from the measurement units were displayed, and the instrument was designed so that, when there was a defect, the location of such a defect could be known.
