Defining Stock Size In BobCADCAM | | In other CADCAM systems beside BobCADCAM you always start by defining your stock size by filling in the X+ X-, Y+ Y-, Z+ Z- for your block size. This enables you to set the proper coordinate system and for the software to determine the correct size for solid model cut part rendering. In addition, because the software knows the size of your rough stock you don't need to waste time creating stock Geometry. It also enables the software to automatically know where to fly cut the part so no Geometry needs to be created for fly cutting either.
CADCAM systems that use this approach show the stock size drawn for the user automatically in wireframe after the numbers have been entered in the stock size text box. This makes programing the job your doing easier and more realistic. If your working with a 4th axis rotary table having a stock size defined helps you to envision where your origins need to be / need to be set. When you change between your defined coordinate systems your stock appears to flip simulating 4 axis positioning which also can be very helpful to programming a part. It's also a easy way to tell the CAM system where the Rotary Table sits so that it can output the correct code. This is also a good place to set a Global Part Clearance Plane and for machines that don't have a tool changer, a tool change position can be set. Finally, why not define the machine the part is going to be made on right up front in this Dialog box.
I have no idea why defining stock size first has not been incorporated into BobCADCAM by now but it needs to be done. Please see the picture that I have attached showing a Dialog box of how other CADCAM systems do this.
