Online Measurement of the Crankshaft Crankpin Roundness Errors in the Process of Coordinate Polishing with Abrasive Tap
The roundness error is researched in the process of coordinate polishing crankshaft crankpin with abrasive belt by measuring online. A detailed study on the tracing motion equations of the measurement system is made，so the mathematical model is obtained in this paper. In order to improve the in-situ measurement precision, the two-sensor tracing roundness error separation principle is proposed under motion stage. Finally, the conclusion that the source of errors could be determined initially according to online measurement of roundness errors is obtained, and then improving the accuracy by changing processing conditions timely.
