Net vs. Gross Flow — LIQUID (also applies to total volume) Gross Flow = volumetric flow rate at actual conditions ('observed') — what most flow instruments measure. Net Flow = volumetric flow rate converted to flow rate at standard conditions — usually 60 deg F. WHY NET? To keep consistent — measure flow at -20 deg F, then product heats up to 40 deg F — different …

What is the Difference Between CNC Milling & Turning?

What is the Difference Between CNC Milling & Turning? The short answer is this – CNC milling uses a rotating tool, while CNC turning uses a rotating part for cutting. So the two use different techniques to create a part. While milling machines create complex parts from blocks of metal by carving away the excess material, turning is commonly used for cylindrical …

Face milling and peripheral milling follow the same concept by using a rotating milling cutter to remove material from a workpiece. The way in which they perform this task, however, varies. So, what's the difference between face milling and peripheral milling?

Boring Vs Drilling: What Is The Difference ...

Knowing the difference between drilling, boring, and reaming will make it a lot easier for you to make holes on an object or workpiece. Ultimately, this will help you achieve a better quality of holes. The main difference is based on how the holes are made. Ultimately, there is a method for each process, and the first hole will need to be made ...

Micro-Milling – The Finer Side of Milling – Pavement ...

An important measure of the surface characteristics of a milled pavement is the ridge to valley depth, or RVD. This is the difference in height between the lowest and highest points of the milled surface. While typical milling drums create an RVD of around 8 millimeters, values for micro-milled surfaces are as low as 3-4 millimeters.
