In manufacturing, especially in industries with a high demand, speed is immensely important. The ability to produce large amounts of product in a short span of time is what gives a manufacturing company an edge over the competition. Companiesthat rely on machine and cutting tool shops often run into a problem because they often think that a higher surface speed will equal a higher manufacturing speed. Although it seems logical, it is actually a fatal flaw.

The thing that people often forget when milling is that the surface speed and types of machine and cutting tool shops in use are dependent on the material. Harder materials require a slower surface speed because the cutting tools can and will break at higher speeds. Sometimes, using a higher surface speed can actually slow down production and affect profitability of the business.Things you need to consider when choosing your surface speed:

Chip Load
The chip load is simply the thickness of the material that is being removed when using machine shop cutting tools. Running your machine too fast will cause the chip load shrink, which may lead to overheating problems. To maximize the efficiency of your machine, use the correct number of flutes on your cutting tools, and do not run at the maximum speed. Keeping the chip load relatively large will prevent your machine from overheating, which in turn will keep the machine running for a longer period. An overheated machine is just going to burn your profits. 

Hardness of the Material
If you are working with a relatively soft material, you can use a very fast surface speed to cut it quickly and efficiently. However, when working with a harder material, caution should be used. Working at a high speed on hard materials can cause your machine cutting tools overheat, wear down, or break. 

Heat Capacity and Strength of the Tools
Choosing the right machine shop cutting tools for the job is one of the most important factors when it comes to milling. A higher surface speed will produce more heat, so you have to make sure that the material of your cutter can withstand it. You also have to consider the strength of your tool compared to the hardness of the material you are cutting. The last thing you want is to wear down or break your tools. Broken tools mean a delay in your production, which can have serious impact on your profits.

To maximize your efficiency, increasing surface speed is not enough and can even prove harmful. It is important to take every factor into consideration when milling parts, so make sure you do your math before you start.
