• ### Speeds and Feeds 101In The Loupe

With miniature tooling and/or certain materials the speed calculation sometimes yields an unrealistic spindle speed. For example a .047" cutter in 6061 aluminum (SFM 1 000) would return a speed of 81 000 RPM. Since this speed is only attainable with high speed air spindles the full SFM of 1 000 may not be achievable.

• ### Grinding Mills Ball Mill Rod Mill Design Parts

Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill. The action of other grinding

• ### CNC Machining Cost Reduction Reduce CNC Prototyping Cost

In most instances the raw material is more economical. Softer materials e.g. aluminum 6061 cut more easily which means less machining time. Harder materials require more expensive tools and are more likely to break and wear tools which can add to the project cost.

• ### How to Calculate Uncertainty Sciencing

In some cases you can easily estimate the uncertainty. For example if you weigh something on a scale that measures down to the nearest 0.1 g then you can confidently estimate that there is a ±0.05 g uncertainty in the measurement.
