Advanced Machining Notes Panel Processing Machines  Common sheet materials o MDF o Melamine – Particle o Plywood  How do achieve “tear-out-free” or prevent chipping when cutting melamine products o Always have good face up o 30° ATB blade o Double cutting (not necessary to use ATB then)  Shallow scoring cut on back surface  Flip and then cut all the way through o Slower feed rate o Blade height just enough to clear the material if new, higher if older/dull o Zero clearance insert o Blade stabiliser  Conventional tablesaw o Advantages  Low cost set-up  Small footprint  Can be used for solid lumber as well as sheet  Can be used to created variety of joints o Disadvantages  Slow production  More difficult to square a sheet  Hard to cut full 4x8 sheets without proper support  Vertical Panel Saw/Wall saw o Advantages  Affordable  Small foot print  Easier material handling  Can cut multiple sheets at once o Disadvantages  Inaccurate at times – moving saw head      Maintenance heavy Shimming required due to gravity – keep kerf open  As the saw cuts along the kerf will close up and can potentially pinch the blade  Newer machines have a vacuum table to hold parts in place Operator fatigue  Walking back and forth pushing the saw along Beam Saw o High production machine  Laurysen Kitchens has one (had?)  Cuts 5 sheets at once o Advantages  Automatically squares sheets  Extremely accurate  Multiple sheets at once o Disadvantages  High installation costs  Large footprint  Only does through cuts, no nesting Rolling Tablesaw o Ours runs a 14” blade  Can cut through preformed countertop backsplash o Cannot be used to cut smaller pieces or solid wood components o Sheet rests on rolling table, easier on the operator o When using the cross-cut fence, the rip fence is drawn back and acts as a stop  Very important to do so or the part will be caught between the blade and the fence o Has built-in scoring blade  Rotates in the opposite direction of the main saw blade – climb cut  Produces a chip-free kerf  Does not have a break  Projects less than 1/8” about 2mm  Can be dropped below the table surface when not needed  Needs to be calibrated after sharpening or after severe kickback o Important to make sure that the riving knife and hood guard are in place when in operation  Make sure that the hood guard is lifted up when tilting the blade o Rip fence is numerically controlled  Decimal inches  Enter dimension and push yellow button  Less than 7 inches need to push and hold yellow button  Safety feature – don’t get squished between the fence and the rolling table o 2 sets of power switches for the saw  One under the table and one on the control pad  White mean go, black means stop  Emergency stop is for emergencies only  Each motor/blade has their own on/off switch o Will turn on independently but when turning off the main blade the scoring blade will also turn off o The scoring blade can be turned off independently of the main blade
