Cutting clearance formula is used to determine the amount of space required between the cutting tool and the workpiece.

• The formula takes into account the tool diameter, feed rate, and material being cut.

• The cutting clearance is important to prevent the tool from rubbing against the workpiece and causing damage.

• The formula is: Cutting Clearance = (Tool Diameter x Feed Rate) / (2 x Material Hardness)

• For example, if the tool diameter is 10mm, feed rate is 0.2mm/rev, and material...read more
