What are the challenges of achieving sharp edges in PVC carvings?
Achieving sharp edges in PVC carvings can be challenging due to several factors. First, PVC is a thermoplastic, which means it tends to melt under high friction during cutting, leading to softened or rounded edges. Second, tool wear is a common issue—blunt cutting tools struggle to maintain precision, resulting in uneven edges. Third, CNC routing speeds and feed rates must be carefully calibrated; incorrect settings can cause chipping or melting. Additionally, PVC's flexibility may cause vibrations during cutting, further reducing edge sharpness. To overcome these challenges, using high-quality carbide tools, optimizing machine settings, and employing cooling techniques can help improve results. Mastering these factors ensures cleaner, sharper edges in PVC carvings.
