Nowadays the cooling systems are more than ever applied into the structure of a machine tool, but unfortunately there are no efforts being made in the control of the cooling systems, which doesn’t allow complete utilisation of their possibilities. This paper presents active cooling control (ACC) system, based on thermal transfer functions, which was experimentally tested on an inbuilt cooling jacke (…)
Milling spindles with inserted 3D tensometric touch probes were applied for on-machine measurement of highly precise parts produced on three - and five-axis milling machines equipped with linear motors and direct rotary drives. New methods of CNC control of angular NC axes during measurement were developed for parts containing hardly accessible surfaces. In-process calibration of multi-directional (…)
One of the main disturbances of the machine tool frame is caused by operation of motion axis. Movement of high dynamic motion axis is connected with powerful force strokes that excite machine tool frame vibration and deteriorate machining surface quality and productivity. There are several possibilities how to suppress this vibration. One possibility is to use suspended motor, where the motor is co (…)
Soaring energy prices, signs of a human-made climate change and legislative pressure have brought the energy consumption of machines to the attention of machine tool builders and their customers. To enable manufacturers and operators of machines to include energy consumption into their considerations in an objective way, we introduce an efficient method to model the energy consumption behaviour of (…)
