(I012)Profile Measurement of Castings for Quantifying Scarfing Depth

摘要

In this paper we propose a measurement algorithm for rigid surface profile called “crisscross light section method” with a view to measuring scarfing depth of running castings. Fluctuation of conveyed castings causes incorrect measurement of surface with existing light section method. The crisscross light section method, on the other hand, enables accurate measurement of whole surface profile under three-axis fluctuation such as vertical or revolving motion. This leads us to expect accurate calculation of scarfing depth. The effectiveness of the proposed method is demonstrated by experimental results.
