Recommended inside bend radius for sheet metal parts should be equal to material thickness. For hard materials (Stainless steel, CRCA), an inside bend radius equal to 0.65 times of sheet thickness is also enough. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material.

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

22.07.2016Design guide for CNC Milling. July 22, 2016. Steven Weinberg. CNC milling is the most common fabrication method for professional prototyping, scaling well into the low- to mid-volume levels and sometimes higher. As with any manufacturing process, the more familiar the designer is the better and easier to produce the part will be.
