Jigs are used to guide cutting tools and fixtures hold workpieces in place during machining operations.
Jigs guide cutting tools to ensure accurate and consistent cuts
Fixtures hold workpieces securely in place during machining operations
Jigs are often used in drilling, tapping, and reaming operations
Fixtures are commonly used in milling, grinding, and turning processes
Limits fits tolerance refer to the range of acceptable dimensions in manufacturing to ensure proper fit and function of parts.
Limits: Maximum and minimum acceptable dimensions for a part
Fits: Relationship between mating parts to ensure proper assembly
Tolerance: Allowable deviation from a specified dimension
Example: A shaft with a diameter of 25mm may have a tolerance of +/- 0.1mm for proper fit with a hole of 25.1mm

Cracking is a process in which complex hydrocarbon molecules are broken down into simpler molecules.
Cracking is a refining process used to convert large hydrocarbon molecules into smaller, more valuable ones.
It is done by breaking the carbon-carbon bonds in the molecules.
Examples include catalytic cracking and steam cracking.
Reforming is a process used in the petroleum industry to convert low-octane naphtha into high-octane gasoline.
Reforming involves rearranging the molecular structure of hydrocarbons to increase their octane rating.
It is typically done using a catalyst at high temperatures and pressures.
The process can also produce hydrogen gas as a byproduct.
Reforming is an important step in the production of gasoline and other fuels in...
The range of a cooling tower refers to the maximum distance at which it can effectively cool air, while the approach is the temperature difference between the cooled water and the entering air.
Range of a cooling tower is typically around 5-20 degrees Fahrenheit
Approach of a cooling tower is usually around 8-15 degrees Fahrenheit
The range and approach of a cooling tower can vary based on factors such as design, size, an
