Spin-Out of Veneer Blocks during Rotary Cutting of Veneer.

摘要

In seeking the cause of spin-out, the torque needed to turn basswood blocks into 1/4-in.-thick rotary veneer was measured for different lathe settings and block temperatures. Increasing the wood temperature reduced the force needed for cutting and also reduced torque that could be accepted by wood blocks before failing by spinout. Maximum torque developed in wood blocks at room temperature depended on the size, number, and shape of spurs on the 4-in.-diameter chucks. Friction drive on the block surface is suggested as an auxiliary source of torque for turning wood blocks into veneer. (Author)
