Circular saw flatness on machine measurement using a point laser displacement sensor

The flatness error is one of the critical parameters a circular saw, which seriously affects cutting performance. In this paper, measurement saw based on laser displacement sensor proposed. For tooth plane discontinuous. According to field detection demand authors collected Archimedean spiral three coordinate data using sensor. Considering practical application detection, have established an ideal model least-squares method evaluate saws. system has maximum area 400 mm × mm, time 80 s, and absolution accuracy 10 μm.
