Microforming method and apparatus |
摘要 |
Method of forming depressions (e.g. dimples) in a sheet material to form a textured surface thereon involves pressing one or more tool tips into a metallic or non-metallic sheet material while the sheet material is supported by a support layer that is relatively softer (e.g. having a lower Young's modulus) than the sheet material so as to allow plastic deformation and reduce pile-up of raised displaced material of the sheet material at the edges of the depressions. |
