When using planetary ball mill, how to select ball size ...

When using planetary ball mill, how to select ball size and how much material should be taken in mill pot? The ball size chosen depend on the impact energy requirement. Bigger balls help in size reduction if the feed particles are big like chunks. If the milling materials are powder, then smaller ball size is preferred.

10 Milling Toolpaths for Your First 2D CNC Machining ...

CNC Milling Toolpaths at a Glance. CNC milling toolpaths are typically categorized as 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.

Optimizing Material Removal Rates - In The Loupe

High Efficiency Milling. High Efficiency Milling (HEM) is a milling technique for roughing that utilizes a lower RDOC and a higher ADOC strategy. This spreads wear evenly across the cutting edge, dissipates heat, and reduces the chance of tool failure. This results in a greater ability to increase your MRR, while maintaining and even prolonging ...

Diving Into the Depth of Cut - In The Loupe - Machinist Blog

Peripheral Milling Styles and Appropriate RDOC. The amount a tool engages a workpiece radially during peripheral milling is dependent upon the operation being performed (Figure 2). In finishing applications, smaller amounts of material are removed from a wall, equating to about 3-5% of the cutter diameter per radial pass.
