Adoption of active power H-bridge filter to vibration compensator for machining processes

Machine tool technology is getting more and more sophisticated in order to achieve high quality and high accuracy of machine tools and fixtures. Different alloys and their properties are generally well known but new ideas for the improvement tool quality are arising. It has been shown that a decrease of vibration during machine tool or other part production increases its precision. This article is about the adoption of known engineering solutions (active power filter- APF) for machining part fixtures during machining processes. The results are extended to other problems where the same circuit-algorithm could be used (e.g. vibration compensation in refrigerators or air conditioners). The active power filter was realized with a microprocessor system (based on TMS320F240). Results were analyzed and further expanded by the software (Simplorer) in order to predict vibration control on different frequencies and for different machining processes. Such a comparison is important in the sense of the price of vibration compensators because integrated electrical circuits with the same algorithm were developed for almost three decades and they have witnessed a break through in mass production because of modern PC production.
