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

Abstract

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

The Flatness Error Evaluation of Metal Workpieces Based on Line Laser Scanning Digital Imaging Technology

“…Xiao et al [28] analyzed and performed compensations for the thin-walled valve body parts' surface flatness by using the contact measurement with the help of the wireless touch-trigger probe installed on the three-axis vertical machine. Wang [29] proposed a way to obtain the circular saw flatness by using the point laser displacement sensor. Although it can extract the point cloud of the measured object via the non-contact measurement method, the efficiency of the measurement is slow, and he just compared the experiment results with the contact measurement result.…”

Pitch and yaw angular speed measurement using Kalman data fusion

“…The measurement of angular speed is a topic because tachometers are required in a plethora of applications across many industries. Many methods and devices rely on counting pulses, which are associated with displacement by a fixed angle [10][11][12][13][14][15][16][17][18][19][20][21]. Most research has focused on the angular rotation speed.…”
