Guide to Cutting Speeds and Feeds: Definition, Selection

Cutting speed, also called surface speed, is the relative velocity between the cutting tool and the surface of the workpiece is being cut. The feed rate is the relative velocity at which the cutter is advanced along the workpiece, or defined as the distance of tool travels during one spindle revolution.

Cutting speed is the spindle speed, while it can be regarded as the speed of tool or the work moves at the point of cut. Based on the different workpiece materials and cutting tools, select a proper cutting speed according to the cutting speed chart for different materials.

What is Cutting Speed,Feed ,Depth Of Cut in Machine tools

The depth of cut is the distance that the tool bit moves into the work. usually measured in thousandths of an inch or millimeters. General machine practice is to use a depth of cut up to five times the rate of feed, such as rough cutting stainless steel using a feed of 0.020 inches per revolution and a depth of cut of 0.100 inch. which would reduce the diameter by 0.200 inch.

How to Choose the Proper Speeds for Router Bits

Many modern woodworking routers allow you to adjust the RPM speed of the motor to match your needs. Choosing a speed can depend on the type of wood you are routing, but also on the type and size of the bit you are using. A tool spinning at too high an RPM may burn wood, while a tool spinning too slowly can leave you with a ragged, rough-cut.

Choosing Jigsaw Blades WOOD Magazine

Choose high-carbon steel (HCS) blades for cutting wood, MDF, or plastic. Though it may dull quicker, this softer, less expensive steel has more flexibility, making it well suited for scroll cutting. High-speed steel (HSS) blades excel at cutting nonferrous metal, as well as acrylics. They have a more durable cutting edge than HCS blades, but additional rigidity can lead to more blade breaks.
