Understanding Shaft Alignment: Thermal Growth
2006-1-3 Machine conditions change from the time the machine is off line to when it is running under normal operating conditions. Some of these changes are due to process forces (e.g., fluid pressures, airflow, etc.). The most notable of these changes is the change in the temperature of the machine bearings and supports. This is called

MEASURING MACHINE TOOLS WITH BALL BARS of the
2009-7-30 machine tool squareness is to be found in the ANSI/ASME B5.54-1992 standard. By any method, measuring squareness comes down to comparing two nominally straight axes for a 90_ relationship. We'll look at a few of them here. Precision mechanical squares are a very economical way of checking a small machine -- up to roughly 24" per axis.

G-Codes Explained: An Introduction to Common G-Code
G-code is the operational language for CNC machining. It tells numerically controlled lathes and machining centers how to move tools in order to perform various cutting operations. It is equivalent to manual programming where each operation is spelled out line-by-line and is separate from M-code and T-code, codes that control the machine and tooling.

Grinding Machine: Types, Parts, Working Operations
Working principle of Grinding Machine: The working principle of a grinding machine is quite easier to understand.. In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley.. So when we start the electric motor the motor rotates at a certain rpm (150-15000 RPM, it may change according to the types of grinding ...

Accuracy, Precision, Tolerance of CNC Machining - BDE
2017-11-24 Consider a CNC machining tool has a tolerance of +/- 0.01 mm. This means that the machining tool can introduce a deviation of 0.01 mm in every cut. This deviation can be either 0.01 mm extra than the standard value, or less than 0.01 mm by the standard value. We hope you got an understanding of the terms – accuracy, precision, and tolerance ...
