Spindle Speed And Feed Calculator5/3/2021
Cut settings dictate to how your machine moves when it carves out a project.Feed rate is the rate at which your machine advances along carve your project.For X-Carve and Carvey, the feed is measured in inches per minute (IPM).Another way to think about feed rate is the distance your bit moves through your project in one minute.
When using Easel with X-Carve and Carvey, feed rate is an independently-controlled motion that will not change if you increase or decrease the rotation per minute (RPM) of your router bit. For example, a feed rate of 20 IPM means your machine advances 20 inches along the x- and y-axis in the course of one minute, regardless of how fast your bit is rotating. Z-axis movements are determined by plunge rate (inches) and depth per pass. If youre interested, you can learn more about Easels feed rate override feature. Depth per pass (sometimes referred to as depth per cut) is how deeply your bit goes into your material every time it starts a new toolpath. For example, a depth per pass of.125 means that your bit will carve.125 deep each time it starts a new tool path. If you are clearing a pocket that is 1 deep, your machine will make a total of 8 passes: (1 total depth) (.125 per pass) 8 total passes As a general rule, we do not recommend using a depth per pass that is greater than half the cutting diameter of your bit. This means that if you are using a bit with a 14 cutting diameter, your depth per pass should be no greater than 18; for a bit with a 18 cutting diameter, your depth per pass should not exceed.0625; etc. This guideline represents the maximum depth per pass for a bit size: most depth per pass settings are much more conservative than these values. Spindle speed is the rotational speed of your bit, measured in revolutions per minute (RPM). If you are using the DeWalt 611 (110v) or 660 (220v) router that comes with your X-Carve, the spindle speed varies from 16,000 RPM at the lowest setting (1) up to 27,000 RPM at the highest setting (6). We recommend staying between the first and second settings for most projects. Chip load is the amount of material removed by each flute (or tooth) on the bit. Larger chips will remove heat from near the cutting area quicker. Removing large chips is useful on materials where melting is a factor, such as acrylics, plastics, and metals. If your chips are too large, you risk breaking your bit because there is too much stress on the tool. ![]() Be careful you arent producing chips that are too small: the materials chips should land on the materials surface or wasteboard, not float in the air like dust. If your chips are too small, you will cause rubbing (also called burnishing). This is caused when the flutes of the bit cannot adequately remove your material and end up just rubbing against it.
