Ball Mill Finish Calculator. The Ball Mill Finish Calculator can be used when an end mill with a full radius (a ball mill) is used on a contoured surface. The tool radius on each side of the cut will leave stock referred to as a scallop. The finish of the part will be determined by the height of the scallop, amd the scallop will be determined by the stepover distance between cuts… Read more

Sandvik recommends starting with a stepover (Cut Width in G-Wizard) of 80% of cutter diameter for the sideways motion of a single pass. The stepover to move deeper into the material for the next pass is limited by the insert diameter or the maximum Cut Width of any non-center cutting tool. 80% of that value is a good choice as well… Read more

Jun 28, 2018 · CNC milling toolpaths are typically categorized 2D, 3D, 4-axis, and 5-axis. However, the term 2D is a bit misleading since this toolpath uses the Z-axis to position a tool for depth. For example, in the image below we have a prismatic part whose features all reside at various heights on the XY plane… Read more

Aug 25, 2015 · A ballnose end mill has a round tip and will produce a path with curved edges. Ballnose end mills are often used for 3D contouring because if you’re cutting layers in several steps, they will reduce the risk of creating jagged steps. You can also increase the step over amount and use a ballnose end mill to cut a wide path with curved edges… Read more

The rule-of-thumb for slot cuts, as an example, is that your depth of cut when cutting a full-width slot should be 1/2 of the cutter diameter. On our machines, it should be 1/4 to 1/3 of the cutter diameter. If you are using a 1/4” end mill, your depth of cut would be between .060 and .080. The same holds true for your step-over amount… Read more
