Safety is always a major concern in a metal-cutting operation CNc equipment is automated and very fast, and consequently it is a source of hazards. The hazards have order to prevent injuries and damage to the equipment n to be located and the personnel must be aware of them Main potential hazards include: rotating parts, such as the spindle, the tool in the spindle, chuck, part in it and the turret with the tools and rotating clamping devices; movable parts, such as the machining center table, lathe slides tailstock center, and tool carousel; errors in the program such as improper use of the Goo code in conjunction with the wrong coordinate value, which can generate an unexpected rapid motion; an error in setting or changing the offset value which can result in a collision of the tool with the part or the machine; and a hazardous action of the machine caused by unqualified changes in a proven program. To minimize or avoid hazards, try the following preventive actions

§ Safety is always a major concern in a metal-cutting operation. CNC equipment is automated and very fast, and consequently it is a source of hazards. The hazards have to be located and the personnel must be aware of them in order to prevent injuries and damage to the equipment. Main potential hazards include: rotating parts, such as the spindle, the tool in the spindle, chuck, part in it and the turret with the tools and rotating clamping devices; movable parts, such as the machining center table, lathe slides, tailstock center, and tool carousel; errors in the program such as improper use of the GOO code in conjunction with the wrong coordinate value, which can generate an unexpected rapid motion; an error in setting or changing the offset value, which can result in a collision of the tool with the part or the machine; and a hazardous action of the machine caused by unqualified changes in a proven program. To minimize or avoid hazards, try the following preventive actions

(1)Keep all of the original covers on the machine as supplied by the machine-tool builder 2) Wear safety glasses, gloves, and proper clothing and shoes (3)Do not attempt to run the machine before you are familiar with its control 4)Before running the program, make sure that the part is clamped properly (5)When proving a program, follow these safety procedures: Run the program using the machine lock function to check the program for errors in syntax and geometry. Slow down rapid motions using the RAPID )VERRIDE switch or dry run the program. Use a single block execution to confirm each line in the program before executing it. When the tool is cutting, slow down the feed rate using the FEED OVERRIDE switch to prevent excessive cutting condition

(6)Do not handle chips by hand and do not use chip hooks to break long curled chips Program different cutting conditions for better chip control. Stop the machine if you need to properly clean the chips 7 Keep tool overhang as short as possible since it can be a source of vibration that can break the insert (8)When supporting a large part by the center. make sure that the hole-center is large enough
