Title: scaling up an old program
Post by: guynamedbathgate on January 22, 2009, 03:44:15 PM

Hey every body. Its been a little while since I have been on. I was wondering if there is a way to scale up an existing program without rewriting the whole thing. I have a design that I'd like to cut at a couple of different sizes.
didnt know if there was a function for that or if I could simply adjust the steps per inch setting to accomplish this task.
wondering what others think is the best way to go about this or if there was already a thread on this and someone could point me at it.

Use the scale DROs at the side of the axis DROs, putting 2 in each x y and z scale DROs will make all dimensions twice the size, putting 0.5 will make it half, putting a -1 in an axis will reverse that axis.

Oh man that is easy. I knew there was a way to do it. It was just one of those use it or loose bits of information.
Thanks :D

one more question, when I do the scaling function, I assume that it also will double my tool offsets as well? so I should say, double the diameter of my end mill when doubling the scaling.
Is this correct?

Now that I do not know, I have only ever used the scaling for my lathe to reverse the code for the X axis when using the front post as opposed to the normal rear turret. I think you will just have to test and see :( unless someone else knows?

I think the tool offsets remain the same only the centerline size changes.
