The U-axis has dual functionality: it can be used as a positioning axis or a free-turning spindle (used when cylindrical grinding). The TTB kinematic allows the wheels to grind above or below the tool. The thermal stability of the machine components is guaranteed by the use of temperature controlled fluids.
The kinematic structure of 6-axis grinding machines for spiral bevel gears is similar to traditional multi-axis machine tools for metal cutting. Therefore, it is reasonable to compensate the 6-axis grinding machine using the modeling and compensation algorithm of traditional five-axis machine tools.
This course will cover the basic principles of machine tool theory. The course will emphasize safety in the machine shop, measurement, metal cutting technology, basic lathe and mill operations, drilling machines, saws, layout procedures, and an introduction to CNC machining. The capability and safe use of machine tools will be stressed.
