Using of versine and sagitta calculations for log sawing optimization, part 1: Circular cross-section

Abstract: Log sawing can be defined as a problem with obtaining squares from a cylindrical shaped raw material, log. There are traditional sawing methods such as live, cant, quarter, etc. for sawmills. However, they cant generally obtain maximum yield due to log and lumber variables for each log. Th...
