Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.

This article will explain what a mechanical seal is and the key design features that make them work. Basics of fluid pump sealing. A mechanical seal is simply a method of containing fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft.
The Sci-Hub project supports Open Access movement in science. Research should be published in open access, i.e. be free to read. The Open Access is a new and advanced form of scientific communication, which is going to replace outdated subscription models.
Electrical issues are often difficult to trace down and quite often the issue might be intermittent and the result of a poor connection. A wire crimp tool is one of the best ways to repair wires causing faulty circuit connections. Investing in a good quality crimp tool …

A nonlinear model of a hydraulic automatic gauge control (AGC) system is established for fault detection and isolation (FDI). By analyzing the relationship between faults and load uncertainties, a decoupling subsystem has been derived using a differential geometric approach. An exponential gain observer has been designed based on the observable decoupling subsystem.
