SurfaceCheck detects surface defects, scratches, voids, and grinder marks on cylindrical parts that may have
been introduced in the manufacturing process. Technologies applied include:
Line scan imaging applied to "unwrap" the OD of a cylindrical part into a single large image
Custom lighting to deal with significant variation of appearance of the defect types (scratches, voids)
Advanced image processing techniques (texture analysis) to deal with the highly varied appearance of the OD surface
SurfaceCheck benefits include:
Parts are 100% inspected for process defects
Voids as small as 0.010" can be detected with a 2K camera (smaller defects can be
identified by upgrading to a larger format linescan camera).
Process improvement by quickly detecting grinder problems (repeated scratches or grinder marks)
Able to detect defects as small as 0.010" with a 2K linescan camera
Able to accommodate part types varying in diameter
Able to process parts at 30/minute
Customizable algorithms for local adaptive thresholding and intelligent defect processing
Customizable user interface for vision and workcell control (including PLC) for operator and line technician including live display and reject buffer display
