The FF-TLOM (Free Form Thick Layered Object Manufacturing) process is based on heated flexible blade cutting of thick foam layers in a free form manner. Both blade ends are supported in a U-shaped tool frame. During cutting the blade is shaped in a minimal strain energy curve. Positioning the tool in an optimal orientation is provided by pitch, roll, yaw and positioning of the tool frame. A restriction of the FF-TLOM cutting is the cutting speed. The cutting speed depends on melting of the foam at the blade location and does not allow outside forces on the blade. Nevertheless the manufacturing time must be as rapid as possible. In this paper an estimation method is proposed for the overall speed setting along a tool path. Hereto the blade is subdivided in blade segments and each segment is analyzed for the encountered speed and in the same time to prevent that the maximum allowable cutting speed is exceeded.
