Name a common defect in machined parts.

• A. Striations
• B. Burrs
• C. Indentations
• D. Cracks

Answer: (B)

Burrs are a common defect found in machined parts, resulting from the cutting process during machining operations. They are thin fragments of material that remain attached to the edge of a machined component after it has gone through processes like milling, turning, or grinding. Burrs can affect the performance and aesthetics of a part, leading to potential issues when parts are assembled or used in applications. In addition to their negative impact, burrs can pose safety risks, as sharp edges can lead to cuts or injuries during handling. Removing burrs typically requires additional operations such as deburring to ensure that the finished part meets the desired specifications and quality standards. Other defects like striations, indentations, and cracks also occur in machined parts, but burrs are specifically associated with the leftover material that results directly from the part's creation, making them particularly relevant in discussions about machining defects.
