| 摘要 |
The present invention relates to a method of manufacturing a case using sheet metal processing, which forms an angular gauge panel on a center of an upper panel rounded in an arc shape while using a metal material. The method of manufacturing the case using sheet metal processing comprises a process of cutting a metal plate using a numerically controlled turret (NCT) punching press, bending the cut metal plate in an arch shape; and then welding an angular gauge panel to the bent metal plate. |
