There will be more information on how to effectively use these tools in the section about cutting strategies. A small corner radius for endmills can also greatly improve the surface finish on floor geometry. This means that the flutes spiral upwards, like they do for typical metal cutting endmills.

This also means that parts with very thin floors may not be suitable for this style of cutter, since the floor can flex up and be gouged by the endmill. Downcut is a practical approach for certain applications. This works particularly well for sheet work. The only exception to this is with PCD tools — those are generally sharp enough to justify the lack of helix. Carbide is definitely the material of choice for cutting tools.

Some shops use diamond-coated cutters, but this is generally better suited for high-production types of jobs. In general, uncoated carbide endmills are the most practical for acrylic. This is because coatings tend to leave a slightly rounded cutting edge, making the tool less sharp. In harder materials, like steel, a slightly rounded cutting edge is an advantage since it makes the edge stronger and less prone to chipping. Overall, the only kind of coating that will usually make sense is a poly-crystalline diamond, or PCD, coating.

If you really want something that will work well, consider a polished endmill. The cutter should be sharp, with aggressive rake angles, lots of clearance, and as smooth as possible. You should also generally avoid tools with excessive radii like round inserts — this can cause rubbing if the feed is too low and then the surface finish will be cloudy. My go-to is a 0.

If the nose rad is large, then the high feed rate required to maintain a clear finish might cause the following problems:. Really, though, all you need is something sharp, and the rest you can figure out fairly easily. There are some polished carbide turning inserts that work extremely well. Note: If you really do need a glass finish on the acrylic, a PCD cutter is your best bet.

For the most part, holemaking is fairly straightforward with acrylic. However, there are a few things to be aware of:. The old-school degree point jobber drills put a lot of heat into the plastic. Work holding needs a lot of surface area, otherwise the part will be prone to cracking or coming loose. For parts that are very flat, double-sided tape actually works very well. This is practical for working with acrylic sheets. It is important that you use equipment properly and that you take safety measures before you get started.

For example, always wear protective glasses and gloves. It is recommended to cool the tool with compressed air. The tool must, of course, be stable and clean. The best milling results are achieved with tools equipped with hard metal or specially coated inserts. The most professional millers clearly have individual preferences for the type of tool, feed rate and speed. We generally recommend tools with two cutting edges, preferably HSS or HM with a clearance angle of 12 degrees or more.

With a tool diameter of 6 to 12 diameter, the speed of around per minute is recommended. With a router, the material under the cutter is free from thickness tolerance. This means that you can calibrate with a router apply a scale. The same speeds are recommended here as with the above milling operations. Edge milling is usually used to clean rough surfaces or to profile them. A polishing cutter is a special form of edge milling. A flat disc with two diamond cutters comes along a clamped plastic sheet, resulting in a high-gloss and optically high-quality surface.
