We have a flat pattern router capable of routing any shape from a full sheet (12 feet by 4 feet). To optimize set-up time and raw material, we take several different parts and cut them out of the same sheet of material. For example, if we need a quantity of 10 pieces of each of the parts A, B, C, D, E, F, G and H (total of 80 individual parts), and all those parts fit on a sheet of material - we will mill them all at once. We will take the individual programs and make a nesting which will cut all the required parts out of one sheet. The nesting spreads out the parts to optimize raw material - so all the part A's are not necessarily next to each other, and all of the part B's are not necessarily next to each other etc. etc. The issue is that the drilling and routing is not optimized within the nesting. For example, if the machine starts to drill 2.5 mm holes in one of the part B's and a Part G is located right next to that part B and also has 2.5 mm holes - the program will not drill the holes in part B and then move on to the part G right next to it; rather it will drill the holes in the first part B and the go drill the holes in all the other B parts (even if they are located far from each other). Once it has finished drilling all the part B's, it will start drilling all the part G's (or whichever other parts have 2.5 mm holes). Is there a way to tell MasterCam to drill the first part and then move on to the closest part which has the same size holes (regardless of the part type)? Any help/advice is appreciated.
