I’ve spent some long days at work recently working on a new upcut saw installation. We just purchased two new saws (one new from the OEM and the other at auction) which are both equipped with a Tiger Stop.
This is a generic pic off of there web site. Ours is set up for right hand operation
This fence system is really a treat…. dead accurate, fast positioning, and in pusher mode, after making a trim cut, it advances your stock (for us a stack of boards) the programmed amount and automatically compensates for the saw kerf to give you finished parts one after another, advancing the stock automatically after each hit of the saw.
We also spent the extra money for a controller upgrade that provides a micro-PC with a touch screen, upon which we are running a program called Clip Board. This enables us to download cut lists from our server, and to optimize the different cuts from the length of stock we choose.
Here’s a screen shot that shows a cut list pulled up and ready to optimize.
And here’s one that shows the optimizer set up to mix and match cut lengths to maximize utilization of the entered stock length.
As you make your cuts, it highlights the items on the cut list, and updates your tally. Each time you actuate the saw, the fence pushes the stock through for the next cut and updates the progress on the optimizer display and the cut list.
It’s looking like the set up is going to do most of what we wanted it to do, and with some extra leg work and creative work arounds, we’ll be able to accomplish the rest.
The new saw is from Vista Machine, and has a 20” dia blade… so we can put multiple stacks of lumber on the conveyor and cut upwards of 12 pieces at a whack.
The optimization program is the cat’s meow though… we ran a cut list of 5 different length items, loading stacks of 16’ long 1×4 on the roller conveyors. When we enter the stock length, the program goes through all the conceivable configurations and automatically determines how many of each part to cut from each run of 16 footers. We’re talking a 2” trim cut on the front edge, then the fence pushes the stock through a series of cuts until the remainder is to short for use. Cutting for a production order of 10 assemblies, the average waste at the end of a board was less than 6”, with the last boards having a 14” scrap piece.
