CNC Routing: Minutes per Sheet
Question
Forum Responses
From contributor B: Our Anderson averages 6 minutes per sheet and this includes drilling for shelves, pilot holes for drawer sockets, lazy susans and plate racks (plate racks used to take 30 min-now 10 seconds) and routing dados. From contributor C: It all depends on what you are machining material-wise and how much machining you are doing on your parts. A sheet full of doweled drawer parts for use takes about 6 to 7 minutes. I have done some engraving and for five 12”x10” signs has taken 45 mins. If you are just running standard cabinet parts with a 0.5 bit with standard drilling patterns you can figure about 4 to 7 minutes per sheet. From contributor D: To contributor B: Since you are doing dadoes, I assume you are using "blind-dado" as your method of joinery? To contributors A and C: What method of joinery are you using on your cabinet parts? Cutting out cabinet parts for a butt joint construction would be faster than say, blind-dado or KD, no? From contributor C: Dowels only - the only dados we do are for case backs. We have a doweling machine that runs on barcode produced by our CNC program. For speed you cannot beat it. From contributor A: Butt joint, staple and screw assembly From contributor B: Yes, we use blind dados. I really like it, but I have only done butt joints and blind dados and have no experience with other ways. It works for me. From contributor E: To contributor A: If you don't mind my asking, how many cabinets does that 4 sheet total per hour produce? And are you optimizing so that you only get 1 full depth base panel per width of sheet, or have you reduced the depth of your base cabinets? From contributor A: I don't mind at all. I'll use the kitchen I just completed as an example. 17 total sheets, 10-3/4" prefinished maple for box parts, 3-1/4" prefinished maple for box backs, 3-3/4" Cherry veneer for finished interior cabinets, slab applied ends, toe kicks, fillers, etc, 1-1/4" cherry veneer for finished interior backs. 17 total cabinet boxes, mostly base cabinets as there was a large island in the kitchen and only a few upper cabinets. My base cabinets are 608mm deep (24"), my base bottoms are only 580mm deep as I run my backs all the way down so I can get a side and a back out of a 48" sheet.
