Sheetmetal Blanking and Forming _____________________________________________________________________________________________ Page 1 of 2 Sheetmetal blanking and forming. Sheet: material of thickness <= 6.35mm (0.25 in), and width >= 304.8mm (12 in). Sheetmetal blanking and forming is a coldworking process, i.e., a process that takes place below the recrystalisation temperature of the metal in question, normally at room temperature. Compared to hotworking processes, the following points are evident. No heating required Better surface finish Enhanced dimension control Improved strength if strain hardening permitted Directional properties may be imparted Historical note: Previously the evolution of a sheetmetal component from conception to production has been a slow, cautious process based on trial and error, craft based skill and experience. Due to the pressures of modern consumer requirements, lead time from concept to production is decreasing, and this, coupled with reduced availability of crafts persons with sufficient skills, increased complexity of components and availability of CAD / CAM systems,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
