Definition

Billet shearing is a chipless production process of raw parts for bulk metal-forming operations by cutting semifinished products as bars and wires into billets.

Process

In the production of steel raw parts for bulk metal-forming operations, billet shearing is the most applied and productive method (Doege et al. 1986). The material lossless process is characterized by a good automation capacity, high production rates, short cycle times of 1 part per second or less, and high profitability in processing diameters up to 120 mm of steel material (Doege and Behrens 2007). Compared to sawing processes shearing is inferior with respect to the achievable billet quality but clearly superior concerning productivity (Oudin and Ravalard 1978). While the profile of the processed semifinished products is mostly circular or square shaped, shearing of multi-edged profiles or tubes is also possible. The shearing process is firmly established in...
