Hello Andy, and thanks for your answer. My idea is to copy or acquire the shape of the lobe using one of those testing machines for camshafts, they have an encoder on the rotational axis and a linear digital sensor to measure the elevation of the lobe as the angle changes. Using this it's very eas

2012-12-13 Thread Leonardo Marsaglia
Hello everybody. I would like to ask to the list, if you know or think about a possible method to create toolpaths around a lobe, using a rotary axis for the lobe, and a linear axis for the cutting tool. Since the tool is intended to be circular, there's no need for height compensation, so one lin
