Image segmentation of grinding cracks in automotive gears

Select a 3D visual sensor and divide the pre processed image data of grinding cracks in automotive gears into gear bodies, automotive gear auxiliaries, and background renderings to obtain the histogram peak value of the image. The pixel threshold range is set based on the histogram peak similarity of...

Tooth profile design of heavy-duty gear rack

The gear rack with large module and heavy load is not suitable for the conventional hobbing and slotting processing method. For small gears, the milling process is usually designed according to the tooth profile, and for racks, CNC cutting or casting is adopted according to the tooth profile. In...
