Due to environmental changes industries are looking for lightweight renewable and degradable material solutions to solve weight and therefore CO2. One highly prioritized topic is the combination of wood materials with plastics. To take advantage of the mechanical behaviour of the wood structure it is necessary to investigate the combination of veneer lumber with plastic (Buchelt et al., 2015, p. 356). Regarding large-scale production an injection moulding process with integrated cutting is addressed in this study. For the process development, it is necessary to comprehend how different wood materials behave in the process step of cutting within an integrated injection moulding process. Recently there are no findings on favourable shear cutting parameters on wood veneers, due to the uncommon application of shear cutting and stamping on these materials (Kollmann, 2017, p. 781; Wagenführ and Scholz, 2018, p. 353). Hence, it is necessary to investigate the behaviour and cutting edge quality of veneer lumber in shear cutting process as a function of process parameters. This work investigates experimentally the cutting force under influence of cutting angle, cutting speed, wood materials and moisture content. Results will be analysed in the context of a subsequently following injection process after cutting.
