Abstract
Systems and methods control abrading operations of an abrading machine by sensing characteristics of an abrading article installed on the abrading machine. When a problem is discovered by sensing the article, appropriate actions may be taken. As one example, the abrading article may be sensed to determine whether the abrading article has been installed with an abrasive side facing the wrong direction. An alert allows an operator to reinstall the article. As another example, the abrading article may be sensed to determine whether splicing tape is present to hold two pieces of abrading tape together. The article may be advanced until the splicing tape is beyond an abrading zone. As another example, the abrading article may be sensed to determine whether the abrading article has stopped moving while the article drive is advancing because the article has broken. An alert allows an operator to repair the break. As yet another example, the abrading article may be sensed to determine whether it is the appropriate grade. An alert allows the article grade to be corrected.
