CNC: machining 2mm acrylic

2013-04-11 12:37 | Categories: CNC

3Starting new section in my blog about CNC machining. There will be notes about machining different parts from various materials. Today I will describe what speeds and feeds I am using to cut 2mm Acrylic (Plexiglas).

 

 

 

 

 

 CNC router (introduction)

 Just to remind you – I am using cheap CNC router from ebay. Here is my setup.

Machining parameters

  • Feed:  350 mm/min
  • Speed: 24000 RPM
  • Cut depth 2mm (2.2 to make sure it cuts through)

 Notes

  • It’s recommended to blow (cool down) cutter with air. Else acrylic heats and instead of cutting it starts melting.
  • Going to slow (feed) – acrylic starts to melt.
  • Going to fast (feed) – cutter starts vibrating (basically because of router is not rigid enough)
  • Climb milling results cleaner surface.

    This post is written in a very good and entails a lot of useful information for me. I am glad to find a good way of writing the post.When you want to build your own CNC machine there are literally thousands of plans and step-by-step websites that offer information on how to do it. The only thing you will have to decide is what type of CNC machine you want to make.
