How to Improve CNC Machining Production Efficiency . We got a highly praise from one of our US customers last week. At the beginning to get the project from this customer, the required lead time is too urgent, it is a big challenging for us. However, we will never to give up any chance to cooperate with a good customer and an excellent project.

OEE can also be calculated using the simple calculation. Formula: (Good Count × Ideal Cycle Time) / Planned Production Time. Example: (18,848 widgets × 1.0 seconds) / (420 minutes × 60 seconds) = 0.7479 (74.79%) The result is the same in both cases. The OEE for this shift is 74.79%.

High speed machining (HSM)–also called trochoidal milling, adaptive clearing, volumill, and more–is a milling technique that can increase material removal rates, reduce cycle time, and increase tool life.

diameter 16-foot-long log is 0.240 inch for a mill cutting dimension lumber (fig. 4a). If the kerf on this log is reduced to 0.180 inch, the pattern shift results in a 2 by 6 rather than a 2 by 4, with an increase in lumber yield from 64 to 69-1/3 board feet–an 8.3 percent increase (fig. 4b). Log Length (Feet)

Last visit: Mon November 29, 2021, 6:31 pm. HEM is a relatively new term. It means High Efficiency Milling. It only became available when constant tool engagement toolpahs became almost standard on most of the CAM software. Unlike HSM that utilizes chip thinning effect, HEM relies on much larger widths of cut and thus chip thinning does not occur.

How to calculate marker efficiency? Marker efficiency is calculated from below formula. Marker efficiency = (Area of all pattern pieces in marker/Total area of marker)*100. Now as per formula, the first coming thing is the area of all pattern pieces. Let's calculate this pattern pieces area. Suppose there are three pieces on the marker.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
