Example #3. N040 G04 F5. This is the same line as above, on the same controller. The decimal changes how the machine reads the code. This is line number 040 of the program. G04 sets the movement mode as dwell. F5 is the amount of dwell time. In this case, 5 milliseconds = .005 seconds. A big difference.
ball mill working principle | Henan Deya Machinery Co., Ltd.
Ball Mill Working Principle. Grinding is usually performed wet, although in certain applications dry grinding is used. When the mill is rotated, the mixture of medium, ore, and water, known as the mill charge, is intimately mixed; the medium comminuting the particles depends on the speed of rotation of the mill and the shell liner structure.

What is Tempering? - Metal Supermarkets
Tempering is performed by elevating the steel to a set point below its lower critical temperature, typically following a hardening operation. Once this temperature is reached, it is held there for a specified amount of time. The exact temperature and time depend on several factors such as the type of steel and desired mechanical properties.

DE-11: Lesson 43. SIZE REDUCTION - e-Krishi Shiksha
For very hard materials, the dwell time in the action zone must be extended, which may mean a lower throughput or the use of a relatively large mill. Hard materials are usually abrasive and so the working surfaces should be made of hard wearing material, such as manganese steel, and should be easy to remove and replace.

Lets talk about the M1 Garand "M2 Ball" Ammo Myth ...
The M1 Garand wasn't designed for any specific loading. It was designed for a specific gas port pressure and dwell time. Port pressure and dwell time are effectively "how hard" and "how long" gas impinges on the op-rod. Since M2 Ball develops the required port pressure and dwell time, it is often cited that the M1 was designed for M2 Ball.
