Quick question. For a mill to move the tool bit from Point A to Point B the software parsing the G Code Xn.nnnYm.mmm determines how fast to accelerate and move each axis so a straight line is drawn between the starting and new end points. Similarly, if an arc is programed the X,Y motion is including acceleration and deceleration to provide the timed step pulses to move the tool in that arc motion.
So with a lathe, the Z is the carriage, X is the cross slide. Again a movement of Z with the idea of forming a taper means the Z and X are specified and the system takes care of accelerating and moving each axis the correct amount and speed so that a taper is cut. For each pass you'd move the X in for the next depth of cut and then specify a relative move again. Spring passes without changing the X starting point. What happens if you want to simulate something like my SouthBend with the taper attachment where turning the carriage handwheel also moves the cross slide along the taper. With MachineKit or LinuxCNC, the JOG keys or MPG moves the carriage. Can the cross slide be programmed track the taper? Is there a way to 'link' the jog buttons so that they track with a mathematical formula? One could manually turn a ball end or some sort of other parabolic curve for example.
