1 2 starboard cnc machine rate • With a 1/2” diameter router bit, feed rates of 12-16 feet per minute are normal. Rates must be slower for material that is 1/2” thick or thicker. Larger bits have higher tip speeds and RPM . CNC lathes typically operate with two primary axes (X and Z) and a spindle that rotates the workpiece. More advanced lathes may incorporate additional axes for complex turning and milling operations. The number of axes in a CNC machine correlates with its capabilities:

• With a 1/2” diameter router bit, feed rates of 12-16 feet per minute are normal. Rates must be slower for material that is 1/2” thick or thicker. Larger bits have higher tip speeds and RPM adjustments may be necessary. • Cut with a circular saw at 1275 RPM using a 50-70-tooth carbide blade. Expect a feed rate of 12-16 feet per minute.
how to calculate cnc speed
I have been machining Starboard (HDPE) for many years (marine industry) with conventional wood working tools and high RPM and fast feeds are the way to go. I have made several items on my CNC and use 100+ipm feeds and 15000+ rpm. 1 1/2 Spoil board bit: 150ipm, 5 plunge, 1mm depth per pass, 1 on Dewalt dial. On the left, a chart designed by Carbide 3D with recommended settings on different materials. Here is another excel chart with reference feeds and speeds.
Current setting is 13000rpm at 10 plunge rate and 100 feedrate. Run as fast as possible (feedrate) and take a lighter cut if you need to to reduce the overall heat. Since Z-height is not changing, you can max out your small machine's feedrate and not worry about backlash or anything like that. Alright 👍 so increase feed rate it is. In this guide, I’ll provide a strategy for calculating your feeds and speeds that uses the formulas for a starting guess and then modifies the numbers based on your specific operation and machine.Right now I'm cutting 1/2 HDPE at 2.5 inches per second at 18000 rpm taking about . 1" per pass. I'm using a single flute 1/4" up spiral but from Onsrud and I'm getting really good results. I've been slowly upping my speed but I feel like where I'm at is really good.
I created a Free CNC calculator to help sort a delicate balance between Feed Rates, Chip Loads, Spindle Speed, and Power that go into finding a CNC setup the optimizes finish quality and minimizes the time required. Plastic typically requires a single flute endmill or 2 flute run at a very low RPM and speed to keep the heat down. I would keep the RPM as low as you can and adjust the feed rate to find the right feed/speed. Carve King, bCNC, Huanyang VFD with 1HP Spindle. while walking around in a Big Box store yesterday pricing materials for an upcoming project, I ran across a product called StarBoard. It's HDPE sheet, 1/2" thick for marine use. It's surprisingly slick and the finished edge had a very nice surface to it. Has anybody ever machined it before?
