Enhancement of vertical turning lathe accuracy by minimising thermal errors depending on rotary table activity and workpiece clamping diameter
Original language description
Thermally induced errors are dominant sources of inaccuracy and are often the most difficult types of errors to reduce today. Software compensation of thermally induced displacements at the TCP is a widely employed technique to reduce these errors due to its cost-effectiveness and minimal demands for additional gauges. Compensation models for machine tool thermal errors were successfully applied on various kinds of machine tool structure and implemented directly into their control systems. The aim of this research is to evaluate an enhancement of vertical turning lathe accuracy by minimising of thermal errors. Thermal errors caused by rotary table speed are nonlinear and a dependency on the workpiece clamping diameter has to be taken into account. Calibration of a reliable compensation model is a real challenge resulting in demands of a dependable verification approach. Techniques using international standard testing and manufacturing of testing workpiece were considered in the research for verifying a practical applicability of the compensation model.
