Nettet3. jun. 2024 · Mean burr height = A/πD, where A is the burr area and D is the hole diameter of the measured burr. In one of the above methods, the measurement of the max–min points of the burr depends on a person and the slope of the burr end point is unstable, which results in the average height measurement. A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process. It is usually an unwanted piece of material and is removed with a deburring tool in a process called 'deburring'.
