Sandvik Coromant says it has extended the functionality of its InvoMilling software so that it will now enable customers to produce both straight bevel gears and herringbone gears. In addition this new version offers a flank correction function. The company says this applies to tip relief and crowning in both the flank and profile directions, as well as helix and pressure angle corrections.
According to the company the user enters the required gear data, and then the CAD/CAM software defines the optimum machining strategies and generates a CNC program that allows the production of different gear profiles using a few standard precision tools.
