Cracking and Chipping: Acrylic is a brittle material, and improper cutting techniques can lead to cracks or chips along the edges. This is especially common when using a feed rate that is too fast or a tool that is not sharp enough. The router bit may cause stress along the cut, leading to unwanted fractures. To avoid this, it’s crucial to use a sharp, high-quality tool and to adjust the feed rate and spindle speed based on the thickness and type of acrylic being cut.
Rough Edges and Poor Finish: Acrylic is prized for its smooth, polished finish, but poor cutting conditions can result in rough, uneven edges. This is usually due to incorrect spindle speed, an inappropriate feed rate, or dull cutting tools. If the material isn’t properly held in place during cutting, vibrations can also create imperfections. To prevent this, it’s important to use a properly calibrated router, optimize cutting settings, and ensure tight clamping of the acrylic.
Melting or Burning: Acrylic is sensitive to heat, and prolonged exposure to high temperatures can cause it to melt or burn. This happens if the spindle speed is too slow or the feed rate is too fast, generating excessive friction and heat. Additionally, a lack of cooling or air assistance can exacerbate this issue. To prevent burning or melting, it’s essential to optimize cooling systems (like air or mist cooling) and choose the right spindle speed and feed rate.
Dust Accumulation: CNC routers cutting acrylic generate significant amounts of fine dust and particles. If not properly extracted, this dust can interfere with the machining process, obstruct cutting tools, and even pose a health risk. Poor dust collection or a clogged dust system can lead to machine inefficiency and safety hazards. A proper dust extraction system should be in place to ensure a clean work environment and maintain machine performance.
Tool Wear and Tear: CNC routers cutting acrylic at high speeds can experience rapid tool wear. The accumulation of heat, friction, and pressure during prolonged cutting can dull router bits quickly, leading to poor-quality cuts and increased downtime for tool changes. Regular tool maintenance and monitoring are necessary to prevent this issue.
Material Warping: Acrylic can warp under heat or improper handling. If the material is not properly supported during cutting, or if the CNC router’s bed is uneven, it can lead to distorted cuts. To avoid warping, make sure the acrylic sheet is securely clamped and evenly supported throughout the cutting process.

While acrylic CNC routers are versatile and efficient for producing clean cuts, issues like cracking, rough edges, melting, and dust accumulation can arise if the correct settings, tools, and maintenance practices are not followed.
