General Mach Discussion / Re: Single Axis question
« on: August 24, 2009, 06:08:31 PM »
To state more clearly. I am using this lathe 12x39 to turn pool cue shaft tapers. The cutting tool is a wood router mounted to the y-axis crosslide which would use a standard stepper encoder motor on linear rails. This axis would not require a great deal of force. However, the problem in actuating the apron or x-axis is the high torque loading and also high cost of components to perform such a task. For tapering there is no reversal or pause within the full toolpath cycle. My hope was to use the headstock and leadscrew locked in time to handle the apron travel. The router is always running so there is no necessary rotational engagement speed. My thoughts are that at the end of one direction of travel , stop the lathe,increase the cut, and without disengaging the leadscrew and simply reverse spindle and leadscrew rotation with one switch. I'm sure easier said or typed than done and dont know if mach3 can be configured. Thanks to all of you guys. Freddy57
