30 ALS 4.0 XE P R O D U C T M A N U A L EN For the most effective optimization and material handling ease, it is recommended to follow the steps below: • Break jobs down into smaller groups of 6-10 trusses • Cut all webs together • Specialty parts (bevels, wedges, sliders, etc.) should all be sent to the ALS 4.0. In most cases, these parts can be cut from one grade/size stock. Figure 42 Turns on the feature that causes the saw to review multiple stock pieces and choose the stock that produces the least waste. Stock pieces to be used can be chosen or revised from the Change Stock screen (Figure 18, Section 3.3.4). ! CAUTION When using this option the operator will have to pay attention to the user interface as to what length and grade lumber to feed into the saw. There are several modifiers that affect the operation of the Optimizer. They are all located on the Optimizing Options panel (Figure 28 & Figure 45, Section 3.5.3): Selecting each option will mark a check in the box. Doing so will result in the following change. • Match Grade Size – With the Multiple Stock Pieces selected (Figure 42), Match Grade-Size can be selected as a modifier. Selecting this feature will request lumber by grade and size. The saw will request like lumber grades and sizes until all of the same stock has been cut. ! CAUTION When using this option the operator will have to pay attention to the user interface as to what length and grade lumber to feed into the saw. • Cut all Within Grade – With Multiple Stock Pieces selected (Figure 42), Cut All within Grade can be selected as a modifier. Selecting this feature will match all grades regardless of size. This will set the cutting order by like grades until a change is required for the remaining stock. NOTE Match Grade-Size and Cut All within Grade are mutually exclusive. Both of these features cannot be turned on at the same time. Using the Optimizer, cutting potential was maximized and waste was minimized. Below is a comparison of an ALS 4.0 and a component saw. The two photos highlight the advantage of using the Optimizer feature on the ALS 4.0. Example: The job chosen for this comparison contained 11 trusses and 121 pieces. ALS 4.0 Stock lengths of 14, 16, and 18 ft. were used. Component Saw Stocks lengths of 8, 10, and 12 ft. were used in all three runs. The job was cut three times with waste longer than 2-0-0, 2-9-0, and 3-0-0 respectively recycled back through the component saw or a radial arm saw. ALS 4.0 WASTE = 0.68% COMPONENT SAW WASTE Recycle 2-0-0: 9.31% Recycle 2-9-0 (above): 11.79% Recycle 3-0-0: 13.87% 3.7.3 Optimizer Options The Optimizer yields the least waste when the following general conditions exist: • The number of different pieces in the job file (the selection pool) is large (250 or more) • There are a wide variety of lengths in the file. The more shorts, the better. • The number of different sizes and grades of stock required for the job is small.
