Simulation Study of the Knife-path Movement for Veneer Lathe Based on Matlab

摘要

The mathematical model of the knife with variablespeed feeding was established, the changing law between the knife feeding speed and the diameter of the log was deduced, the calculation method of the peeling time was also derived, the formula based on pitch angle of the knife is given. The mathematic model among the pitch angle, diameter of log and height position of the knife was established in the paper, there was a simulation with the help of MATLAB software. The study shows that, in rotary cutting process, in order to achieve the optimization of the rotary cutting, when the knife was fed at variablespeed it must be rotated with pitch angle, the pitch angle is influenced by height position of the knife, the results of study will provide a guide for the control system design.
