what is the difference between rubbing compound and cutting compound?

Rubbing compounds basically targets the uneven car's surfaces caused by scratches while on the other hand; polishing is preferably used for adding smoothness and shine to the car paint. Both will help in improving your car's quality but in a different way.

Define the difference between roughing and finishing operations in machining. A roughing operation is used to remove large amounts of material rapidly and to produce a part geometry close to the desired shape. A finishing operation follows roughing and is used to achieve the final geometry and surface finish.

Cutting motion (CM) can be imparted by rotating or oscillating the workpiece or cutter. This CM basically imparts necessary cutting velocity; while feed motion (FM) imparts necessary feed velocity. Cutting speed (N) and feed rate in straight turning in lathe is shown here.

Better lubrication usually means less power loss and less friction. But the relationship to surface finish is not always the same. Better EP and AW additives should result in better surface quality, but these additives doesn't necessarily increase lubricity performance.

The difference between these two techniques is the relationship of the rotation of the cutter to the direction of feed. In Conventional Milling, the cutter rotates against the direction of the feed. During Climb Milling, the cutter rotates with the feed.

Some common uses for abrasives include grinding, polishing, buffing, honing, cutting, drilling, sharpening, lapping, and sanding (see abrasive machining). (For simplicity, "mineral" in this article will be used loosely to refer to both minerals and mineral-like substances whether man-made or not.)

Cuts and scratches are areas of damage on the surface of the skin. A cut is a line of damage that can go through the skin and into the muscle tissues below, whereas a scratch is surface damage that does not penetrate the lower tissues. Cuts and scratches may bleed or turn red, become infected, and leave scars.

The most commonly used abrasives are hydrated silica (softened silica), calcium carbonate (also known as chalk), and sodium bicarbonate (baking soda). Other abrasives include dibasic calcium phosphate, calcium sulfate, tricalcium phosphate, and sodium metaphosphate hydrated alumina.

A cutting fluid us used to lubricate the cutting edge of a tool as well as carry away heat . ... A coolant may or may not also act as a cutting fluid and is primarily used to cool the cutting operation. It will serve as a means of flushing away chips and sometimes that and cooling is its only task (like an air blast).

Most barrel manufacturers move from deep hole drilling to reaming, a process that leaves tool marks in the bore. Instead of reaming, Bergara uses three separate honing spindles that utilize diamond tipped bits. These bits polish the interior surface of the barrel to a mirror-like finish that is almost flawless.

Unlike the metal drill bit, there's many different types of bit that can drill wood and timber. ... Also unlike wood no lubricant is used with wood, although beeswax can be used to lubricate anything cutting through wood. Masonry drill bits. Once again with the masonry drill bit, lubricant isn't really used.

Lubricant is the generic term for all substance that are used to reduce friction and wear in moving/rubbing surfaces. While oil is the common liquid or fluid lubricant to do this job. A grease is a solid lubricant which also do the same function as oil but stays in place to provide the lubricating function.

The only difference between cut+paste and copy+paste is that copy duplicates the file in a new location and stops, cut duplicates the file then deletes the original. So cut has one more operation which will take a little longer, but not significantly.

With the rip cut, you cut along the grain; while with the cross cut, you cut across the grain. Cutting along the grain is a very easy cut; even before you had mechanical saw, you had saws with few but large teeth so you cut as fast and as straight as possible.
