Measurement and mathematical simulation of planed and spindle moulded product surfaces

This paper has identified the mathematical relationship that exists within the planing and spindle moulding process. The paper has also explores the basic kinetics of the process and has detailed the development of an automatic monitoring system. The developments described will allow the woodworking industry to fully understand the process and monitor the surface quality of manufactured products, in-process and without damage. The automatic monitoring system has been verified using both a classical stylus surface measurement instrument and the computer simulation which utilised the trochoidal relationship that has been shown to exist between cutter tips of the machine and the traversing workpiece.
