The depth of the cut and the feed rate will also affect the cutting speed, but not to as great an extent as the work hardness. These three factors, cutting speed, feed rate and depth of cut, are known as cutting conditions. Cutting conditions are determined by the machinability rating. Machinability is the comparing of materials on their ability to be machined. From machinability ratings we can derive recommended cutting speeds. Recommended cutting speeds are given in charts. These charts can be found in your Machinery’s Handbook, a textbook or in a chart given to you by your tool salesperson. In Table 4 you will find a typical recommended cutting speed chart.

Written in a straightforward, conversational style, this comprehensive textbook offers a hands-on introduction to materials science and manufacturing techniques. You will explore metallic and nonmetallic materials, their properties and applications, and how products are made from them, including traditional, additive, and advanced manufacturing methods. Materials and Manufacturing: An Introduction to How They Work and Why It Matters starts off by explaining materials science fundamentals and progresses to outline manufacturing processes in the order in which they are often employed.

Cutting speed for steelwith carbide

Since the available spindle speed settings are generally not infinitely variable, the machine cannot be set precisely to the calculated RPM setting. Some judgment must be made in selecting the speed to use. Try to get to the speed which is nearest to the calculated RPM, but if you can’t, consider these conditions. Are you roughing or finishing? If you are roughing, go slower. If you are finishing, go faster. What is your depth of cut? If it is a deep cut, go to the slower RPM setting. Is the setup very rigid? Go slower for setups that lack a great deal of rigidity. Are you using coolant? You may be able to go to the faster of the two settings if you are using coolant. The greatest indicator of cutting speed is the color of the chip. When using a high-speed steel cutter, the chips should never be turning brown or blue. Straw-colored chips indicate that you are on the maximum edge of the cutting speed for your cutting conditions. When using carbide, chip colors can range from amber to blue, but never black. A dark purple color will indicate that you are on the maximum edge of your cutting conditions. Carbide cutting tools are covered in much greater detail in other sections of your learning materials.

There are rules and principles of cutting speeds and R.P.M. calculations that apply to all metal cutting operations. The operating speed for all metal cutting operations is based on the cutting tool material and the hardness of the material to be cut. In this unit we will concentrate on cutting speeds for single point tooling.

The hardness of the cutting tool material has a great deal to do with the recommended cutting speed. The harder the cutting tool material, the faster the cutting speed (figure 3). The softer the cutting tool material, the slower the recommended cutting speed.

This simplified version of the RPM formula is the most common formula used in machine shops. This RPM formula can be used for other machining operations as well.

Which wheel traveled farther? The larger wheel traveled farther because it has a larger circumference and has more surface area. Cutting speeds work on the same principle. If two round pieces of different sizes are turning at the same revolutions per minute (RPM), the larger piece has a greater surface speed. Surface speed is measured in surface feet per minute (SFPM). All cutting speeds work on the surface footage principle. Again, cutting speeds depend primarily on the kind of material you are cutting and the kind of cutting tool you are using. The hardness of the work material has a great deal to do with the recommended cutting speed. The harder the work material, the slower the cutting speed. The softer the work material, the faster the recommended cutting speed (Figure 2).

Searching for just a few words should be enough to get started. We’ll suggest common engineering terms as you type.

Note that in the R.P.M. calculation, we used the diameter of the drill and not the workpiece. This was done because the cutting takes place at the diameter of the drill, not on the outside diameter of the workpiece.

A turning operation is to be done on a 3.00-inch piece of 4140-alloy steel with a brinnel hardness of 200. A carbide turning tool is to be used. Calculate the RPM setting to perform this cut.

The lathe R.P.M. must be set so that the single point cutting tool will be operating at the correct cutting speed. To set the proper speed we need to calculate the proper revolution per minute or RPM setting. We stated earlier that cutting speed or surface speed would change with the size of the part. So to keep the surface speed the same for each size part we must use a formula that includes the diameter of the part to calculate the proper RPM to maintain the proper surface footage.
