Study of Tracking System of Tool Position in the Machining Facility

Abstract

We propose a tool position tracking system in a machining facility. It will be able to track tools that are hidden under other objects. We will also research the frequency of processing that gives practical tracking accuracy.

When the tool is hidden or cannot be recognized by the camera, system recognizes that it is in the same position based on past location information and continues tracking.

We checked accuracy based on the degree of match with visual tool tracking. We experimented with the case of one and two workers. The tracking accuracy of this study was higher than track method of only visible tool. In the case of one worker operation, for intervals less than 8 seconds, the tracking accuracy was over 95%. In the case of two workers operation, even at the maximum frequency of the processing, the tracking accuracy was 90%.

The target for tracking accuracy was not met. However, we were able to track tools that are hiding under other objects.
