Rigid foam is so soft that you can practically crank up the feedrate to full tilt without worrying about breaking an end mill. Metals need slower spindle speeds to avoid overheating, for example. Of course, the hardness of the material plays a major role in the proper feeds and speeds. What you want is the Goldilocks zone: a spindle speed fast enough to cut easily and a feedrate that's as fast as possible without risking too much lateral strain: If the feedrate is slow and the spindle speed is faster than it needs to be, there will be little risk of breaking the end mill, but the job will take longer than it needs to: If the feedrate is fast and the spindle speed is too slow, the end mill will break under the lateral pressure: The goal here is to optimize the feeds and speeds so that your work is cut as quickly as possible without breaking the end mill.

Units are revolutions per minute or RPM.Īll of the other variables (Cutting Feedrate, Feed Per Tooth, etc.) will update automatically when you adjust these two.Spindle Speed: The rotational speed of the spindle.

Units are distance / time, usually in/min or mm/min.

Feedrate: The distance the spindle moves relative to the time it takes to move along the workpiece.

You will see lots of variables in the Tool tab of the Toolpath window, but I want you to pay close attention to just these two when you're getting started in CNC: The basic settings can be summed up in terms of "feeds and speeds". When you're running a CNC mill, it's important to have the proper settings. I set all of these offsets to 0 because I don't want to leave behind any stock. The Stock tab will show a default offset in each dimension. To set the origin, you can click Origin and select Model Origin, or you can click on the origin point (white ball where X, Y, and Z meet) of the CAM axis and click again on any point on the model or on the model origin if your piece is placed on it. If the X or Y axes aren't pointing the right way, you can flip them by clicking the ends of the arrows. The CAM origin should now be set with Z as up, X pointing to the right from this point of view, and Y pointing to the left along the base of the model. You can click the arm of the Z axis, then click the up-axis on the model origin ( NOTE: The model origin has to be turned on in the MODEL workspace). To change the axis, just click on the arm of the Z axis arrow, then click any line in the model Y axis.

The Axes will be based on the model environment in which Y is the "up" axis, but for CAM, Z has to be the "up" axis. A generic stock will automatically be created and represented as a translucent box around the solid object. First, switch to the CAM workspace in the workspace drop-down list on the upper left of the interface.
