Step 1
Acrylic can shatter and break easily; always ensure the correct cutting speed and feeds are selected when turning on a centre lathe.
Answer
When machining acrylic, it's critical to use the appropriate cutting speeds and feeds. This helps minimize the risk of the material shattering, ensuring a safer working environment.
Step 2
When drilling, ensure the acrylic sheet is supported underneath and reduce feed to help the drill cut through successfully.
Answer
Supporting the acrylic sheet fully while drilling prevents it from cracking. Additionally, reducing the feed rate allows for a cleaner cut, enhancing safety and the quality of the work.
