How do you calculate saw cutting time?

How do you calculate saw cutting time?

Take half the diameter (radius) multiply it by itself. Then multiply that by 3.14. Example: 20˝ bar. Half the diameter is 10˝.

How thick can a band saw cut?

Band saws are the undisputed champ when it comes to cutting curves and slicing through thick material. Many small band saws can slice though lumber a full four inches thick, and bigger saws handle six-inch cuts.

Will a bandsaw cut cast iron?

It depends on the quality of the cast iron. Some will take SEVERAL minutes to do it, and others will take a lot longer, but none will take a couple of minutes. I have had cast iron that a band saw cut in a couple of minutes and other pieces that took the teeth off the blade without making a mark on the pipe.

What is a bandsaw throat?

The throat is the distance from the blade to the vertical frame section of the body of the saw. This distance determines the width of cut that can be completed on the band saw. The throat on a free-standing cabinet band saw typically exceeds the 12 to 14-inch throat of smaller, bench-top models.

How do you measure bandsaw cutting time?

Looking in a simple table one can find that SS 2343 should be cut with a cutting speed of 25 to 35 cm 2/min. With some effort the minimum cross section of the bar is calculated as A=πr 2=78 cm 2 and the minimum cutting time is then calculated as 78/35 to 78/25=2.23 to 3.24 min.

What is the formula for determining the cutting speed of a band saw?

The formula to determine S.F.P.M. is: Motor RPM multiplied by the Motor pulley diameter divided by the Driven pulley diameter times the Bandsaw wheel diameter times pi (3.1416) divided by 12 = S.F.P.M.

How many teeth does a bandsaw blade have?

The general rule of thumb is: For wood and soft materials aim for 3 – 6 teeth in the workpiece. For metals and harder materials aim for 6 – 24 teeth in the workpiece.

Can a cordless band saw cut metal?

A cordless band saw model can also be used to cut metal. When using this model, you must secure the work-piece then align it with the blade. Position it at a line on which you need to cut.

How does a band saw blade work?

This blade works in only one direction different from some saws that work with an up and down movement. In general, band saws are not produced for cutting thin metals, it is recommended that the metal must be thicker than the depth of 3 teeth of the band saw’s blade.

Why do band saws have teeth per inch?

Henceforth, blades that possess more teeth per inch result in smoother cuts, and blades with fewer teeth per inch result in lighter work when cutting thicker metals. Many models of band saws are available out there.

What is band speed on a table saw?

Band speed refers to the rate at which the blade cuts across the face of the material being worked. A faster band speed achieves a higher, more desirable shear plane angle and hence more efficient cutting. This is usually stated as FPM (feet per minute) or MPM (meters per minute).
