Increasing tool life during turning with a variable depth of cut

The article deals with the improvement of cutting-tool durability by using CAD/CAM systems. It proposes new roughing turning cycles where a variable depth of cut is applied. The experimental part verifies theoretical prerequisites when a flange is being machined with a sintered-carbide cutting tool. It compares the turning where the standard roughing cycle is used and the turning where the proposed roughing cycle with a variable depth of cut is applied.
