Calculation of Technological Limits in Designing High-Speed Operations

Abstract

The paper considers the technique of technological limit calculation for high-speed operations on CNC machines. The relationships between the parameters of the technological system and pre-set limits are calculated and presented graphically. An impact of radial tool feed on the workpiece surface undulation, required drive power, tool wear, workpiece surface temperature, and elastic strain values is demonstrated. The methods of calculating the technological limits are developed to ensure the accuracy and surface quality requirements with regard to technological capabilities of the equipment and tools. The technique is invariant and works either when all the limits exist or some of them. Consequently, the calculation of limits will be performed in dependence on the design environment for each specific machining conditions.
