Timber product surface analyses and potential solutions related to the vibration problems of a wood planer and moulder

High speeds of operation of woodworking machines result in high level of noise and vibration. A study of the geometry of, and the mechanics associated with, the production process presented in order to generate a mathematical model which can be used to represent the geometry of a spindle machined surface. This technique can also be used to predict surface profiles. A mechatronic solution ensuring consistent surface quality is to develop intelligent control of electro-hydraulic servo systems, which vibrate the cutter head in anti-phase to cancel out the inherent mechanical forced vibrations. To fulfil the task, an optical-laser noncontact in process measuring system is developed, and a hydraulic digital valve is employed as an actuator which can meet the needs of quick response and high switching speed performance
