Tutorial Exercise #5 mill level 3 missing dimensions

[weisshahn]

I am studying this leason and the exercise portion of it is missing some critical dimensions. Mainly the size of the pockets,and location of at least the center of it. Maybe i am missing something. Any help would be very much appreciated! Than You

I ran in to the same problem, what I did was assumed the pocket center on x from top view was center line. then the Y would be ((4-2.7)/2)+2.7. That will give you center between 2.7 and 4 which is 3.35. So x=0 y= -3.35 center of square. On the rest it is mostly guessing on what looks good. The important thing is getting the tool path right. If your geometry is off that is okay. For the most part the path will turn out okay.

 

BTW, didn't your book come with a CD so that you can run the sample file. My experience with MasterCAM is, drawing isn't where you spend most or even half of your time. If you get your tool paths down and understand why then you will be golden.
