Abstract

Experience gained in the use of high speed machining to manufacture tensile specimens in sheet metals, for the purpose of characterising the dynamic mechanical tensile properties is described. The dynamic properties of a sheet
material are used in digital design tools by the automotive industry to support development of products with safety critical imperatives. The paper identifies the quality requirements to manufacture tensile specimens in sheet metals and alloys for the purpose of characterising their dynamic mechanical properties. The benefits of high speed machining over conventional machining to manufacture tensile specimens with varying dimensions are summarised. A low cost method to manufacture specimens in a range of sheet metals and alloys to meet the quality requirements of manufacture is described.
