Sensor technology in the process of the workpiece
Compared with the process supervision technology of tools and machine tools, the process supervision of workpieces is the earliest and most studied and used. Most of them are based on the quality control of workpiece processing. Since the 1980s, the identification of workpieces and the positional supervision of workpiece equipment have also been on the agenda. Roughly speaking, the process identification is a process for identifying whether the processed process is a machining (zero) machining request; the workpiece identification is to identify the workpiece to be processed into the machine tool or whether the blank is a workpiece or blank to be processed. Together, they also asked for the position of the workpiece device to be the position desired by the process. In addition, workpiece identification and workpiece equipment supervision can be used to sense the machining margin and surface defects of the blank or workpiece to be machined. At the end of these identification and supervision, many sensors will be selected or developed, such as machine vision sensors based on TV or CCD, laser surface roughness sensing systems, and the like.
Tool (grinding wheel) viewing sensor
The cutting and grinding process is the primary data removal process. The tool and the grinding wheel wear to the limit (determined according to the blunt specification) or appear damaged (general name of damage, chipping, burn, plastic deformation or roll cutter), so that they are lost (grinding or can not ensure machining accuracy and machined surface) Integrity, called tool/grinding wheel failure. According to industry statistics, tool failure is the primary factor leading to machine tool failures, and the downtime caused by it accounts for 1/5-1/3 of the total downtime of NC machine tools. It may also cause equipment or personal safety incidents, even major accidents. Tool inspection sensors can be useful to prevent such operations from occurring.
