Cabinetmakers use table saws, radial arm saws, band saws, panel saws, and scroll saws to cut wood and composite materials. Although sawing is also an integral part of other cabinetmaking opera- tions, such as joint making, this chapter focuses on the challenges of sawing to size and shape. Stationary power-sawing machines are designed for either straight-line or curved-line cuts. However, saws used to cut curves can also cut a straight line, if a straightedge or fence is used. Selecting the proper saw involves several decisions: • Select the safest saw for the cut you want to make. • Choose an appropriate saw for the cut. • Have prior instruction and experience with the machine. • If more than one saw is appropriate, choose the one that is most efficient. Once you have chosen the machine, consider the following suggestions for safe and efficient opera- tion of the saw: • With the switch off, disconnect the power and lock out the machine before performing major setup steps, such as changing blades and setting the fence. • Be sure the saw blade is clean and sharp. • Install and adjust point-of-operation guards. • Support material before and after the cut. • Feed material into the saw properly. • Ensure dust collection is operating.
