Material Removal Aspects and Cutting Power Requirement of Profile Independent Wood-Moulding

Abstract

This paper investigates the cutting power requirement for the Profile Independent Wood-Moulding Machine (PIMM). Chip severing phenomena is described and the factors affecting the cutting forces in rotary wood machining are surveyed. The nature of material removal and the influences of PIMM's machining parameters on cutting forces are theoretically investigated. Purpose designed cutting power measurement setup is explained and experiment results are discussed. The findings provide a foundation in the design process of a dedicated cutter for the PIMM in order to achieve optimum production rate.
