Re: [CAD_CAM_EDM_DRO] Cam program and post needed for a cnc propellor carving lathe

Larry,
 
Might be easier to just go with a 3 axis CNC router and ordinary cad/cam software.  The cnc router might also be useable for other parts.
 
Another old fashioned alternative would be a duplicating mill which allows you to duplicate a hand made blade.

I am interested in building a cnc propellor carving lathe to create
wooden wind turbine blades, one blade at a time. The proposed lathe
would be run with Mach 3 and 2 axis control having a servo motor
drive on the headstock spindel and one on the cross slide axis. There
would be gearing and a lead screw to slave the Z axis from the spindel
at the rate of .125" per revolution.The cutting tool would be a 10"
dia. carbide table saw blade that would move in and out on the cross
slide X axis as the spindel rotated continuously.
I have use of a program that will create an STL. file of the
blade.But I need to learn of a cam program that will let me define the
axis of rotation and has a post processor for a machine of this
configuration.
Thank You, Larry Reiss Omaha, Nebraska
