the Correction Factor (CF) to obtain the %LEL of the gas being measured. 2. Calibrate the unit with Methane and then call up the Correction Factor from the instrument memory or choose the Correction Factor from the instrument memory first and then calibrate to methane. The unit after that reads directly in %LEL of the gas of interest. 3.
In a milling operation, the Chip Thickness varies between the point of entry (A) and the Point of Exit (C).; At the Point of Exit (C), the thickness is always Zero. When the radial depth of cut (Ae) is larger than the cutter's radius, the chip thickness starts with a certain value. It gradually grows unit it reaches its maximum thickness at the cutter's center (B).
