New Pics at Tauseef Pics

Hi everyone! hope all is going well. I finally got a chance to
machine a little. I would like to share some pics of my rotarty table
in action.

The pictures are in the FOLDER "4th axis candle pics."

Setting and holding the "soft" candle was the hardest part of making
this. Overall its drawn in XY coordinates with the rotary table
plugged into the Y axis. The circumference of the candle is set as
the length of the "Y" axis so it cuts out right. I used a flat
endmill and the candle I made before (cut to 6 mm deep) showed
many "undercuts." I finally realize why "rotary compensation" would
be usefull. When the cutter moves 6 mm into the material a 1mm
movement is not the same amount as now the radius is 6 mm less. Rich
suggested a tapered bit and I think thats a great idea.

The rotary table is a standard sherline that I made mounts for. The
backlash is taken out by putting the worm and rotoary gear as close
as possible without binding and then tightening the screws. I then
measured backlash 90 degrees apart and averaged the 4 numbers...this
is set in cncpro.

thanks guys

P.S. Take it from me all of you newbies....it is possible!
