Final answer:
The margin of safety for a Radial Arm Saw is the recommended distance between the saw blade and any obstacle, based on the maximum movement of the blade. The newer work suggests a margin of safety as much as 8 diameters side-to-side and 15 diameters deep. It is important to maintain this distance to ensure safe operation.
Step-by-step explanation:
The margin of safety for a Radial Arm Saw refers to the recommended distance between the saw blade and any obstacle, such as a wall or workbench, to ensure safe operation. It is based on the maximum movement of the saw blade and is typically expressed as a factor of the diameter of the blade.
According to the given information, the newer work suggests a margin of safety as much as 8 diameters side-to-side and 15 diameters deep. This means that for a saw blade with a diameter of D, the recommended distance from the blade to any obstacle should be at least 8D side-to-side and 15D deep.
For example, if the saw blade has a diameter of 10 cm, the margin of safety would be 80 cm side-to-side and 150 cm deep.
