This standard specifies safety requirements for the design, construction, operation and maintenance (including installation, dismantling and transport) of gear and spline cutting machines (see 3.1). The requirements of this standard apply to machines with single or multiple spindles that are specifically constructed to produce gear teeth by the process of hobbing, milling, shaping, and broaching. It also applies to those machines that shave, hone, lap, or chamfer gear teeth and machines used to produce ratchet, spline, or sprocket teeth. The requirements of this standard do not apply to machines used for molding, rolling, flame cutting, gear grinding, stamping, impact forming, forging, and gear inspection. Power tools, portable by hand are also excluded from this standard.
