Burr tolerance standards
WebTolerancing Most common steel grades are offered in standard gage thicknesses and tolerances. These sizes are usually readily available as stock items and are generally the best choice when cost and delivery are a major factor. Rolling mills work from master coils, and so usually have minimum order quantities, somewhere in the truckload range.

WebThis International Standard defines the terms defining the states of edges and specifies rules for representing states of edges of undefined shape in technical drawings. The proportions and dimensions of the graphical symbols to be used are also specified. WebA burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process. [1] It is usually an unwanted piece of material and is removed with a deburring tool in a process called 'deburring'. Burrs are most commonly created by machining operations, such as grinding, drilling, milling, engraving or ...

These parts define mechanical precision levels to simplify technical drawings. Part 1 – General Tolerances for linear and angular dimensions. The precision here is defined as fine, medium, coarse, and very coarse. Part 2 – Geometrical tolerances for features.
WebStandards development is a process that involves many individuals, companies, and often governments. They advance the adoption of emerging technologies and guarantee the state of the art guidelines to respect safety requirements.

For sheet-metal parts with a thickness ≤ 3 mm, a general requirement allowing a maximum burr size based on the material thickness can be applied as an alternative to indications according to ISO 13715.
WebBurrs are an undesired and unavoidable by-product of most conventional manufacturing processes, such as cutting, forming, blanking, and shearing operations, because of the plastic flow of material. A burr is defined as a projection of undesired material beyond the desired machined features (125).
WebThis also means that tolerances in the title block of a drawing may be unnecessarily restrictive for certain dimensions and angles, while very appropriate for others.
