Hey there folks,
I stayed late today at the shop to finish up the blades for heat treat.First I surface ground them to within .005 of finish thickness.
Next I wrote a program in MasterCam to do a 3D sweeping contour profile using a .125 diameter carbide ball mill. I manipulated the amount of step over, and across step in the program parameters to achieve the rippled/fluted effect on the blade. I was able to use the same program for the opposite side after turning on the mirror image function on the CNC control.
I don't know about you, but I'm digging them...:)
Thanks for looking, Kenn
