I have CNC'ed my cold saw
« on: May 07, 2015, 01:50:56 AM »
I bought a manual cold saw this year that I've updated with a ball screw feeder and an electric cylinder made also with a ball screw.

Work OK for now but will need some help to program the feeder, feeder have about 30in of travel with limit switches at both end.

There is a pneumatic vice on the feeder and on the saw.

I've added 4 buttons on the screen, Open and close feeder vise and 2 others for the saw vice.

Both vises can also be actuated with 4 macros for programming, M200, 201, 202 and 203.

What I would like to achieve, is when the feeder is near the limit switch, would return at the starting point and continue feeding the stock.

Will update this thread with pictures, camera still in the shop and I'm at home right now.

Hi Jeff,
  I'm anxious to monitor the progress of your project as well.
I recently finished something very similar .... with the help of the fine folks on this forum.  :)

We used a macro to divide the full available stroke of the feeder by the feed length of the individual part, then retract the feeder for the maximum number of cuts allowable per full stroke. Then, feed-cut, feed-cut, feed-cut ..... till the end, then repeat.
REALLY saved a lot of time while not allowing the feeder to move while actually cutting.
Can easily hold the finished cut lengths to less than +/- .0008"


Keep us in the update loop.
Regards,
Russ

Another one

I'm not very good at VB program, I can do simple things but, when it comes to something like that, I'm completely lost.

I can program it to cut parts easily but, it's very time consuming and not very productive.

Thanks for your replies.
