Have you ever wondered why some CNC-milled prototypes exhibit smooth finishes while others display wear and imperfections? According to a recent survey, nearly 30% of manufacturers report surface quality issues in their CNC processes, hindering production efficiency and increasing costs. With trends in customized manufacturing on the rise, understanding how to maintain the surface quality of CNC-milled prototypes is critical. This blog will dive deep into effective strategies to prevent the deterioration of surface quality in CNC milling, ensuring your prototype meets high standards.
Understanding CNC Milling and Surface Quality
Before discussing solutions, let’s clarify what CNC milling is. CNC, or Computer Numerical Control, milling involves using computer-controlled machines to subtract material from a workpiece to achieve desired shapes and dimensions. The surface quality is a crucial aspect of this process, determined by factors like tool selection, feed rate, spindle speed, and material characteristics.
Understanding these factors can provide insight into why surface quality might degrade during milling. Issues can stem from a variety of sources, including tool wear, incorrect cutting parameters, improper machine calibration, and even the age of tooling equipment.
