How Tool Life Depends on Feed Rate?
Tool Life varies with feed rate. At a low feed rate, the area of the chip that passes across the tool surfaces will be relatively large for a given volume cut, and relatively small for a high feed rate.
From this, it seems that tool life should increase with the increase in feed rate, but as the cutting forces on tools also increase with the increase in feed rate, it leads to decreased tool life. Thus these two opposing influences of the feed rate upon tool give rise to an optimum rate of feed which is about 0.25 to 0.50 mm/rev.
How to Calculate Feed given Cutting Velocity, Tool Life, and Volume of Metal Removed?
Feed given Cutting Velocity, Tool Life, and Volume of Metal Removed calculator uses Feed Rate = Metal Removed Volume/(Life of Tool*Cutting Velocity in Tool Life*Cutting Depth) to calculate the Feed Rate, The Feed given Cutting Velocity, Tool Life, and Volume of Metal Removed is a method to determine the valid feed rate that should be applied to the tool so as to obtain the Allowed Volume of Material removed hence the optimum tool life. Feed Rate is denoted by f symbol.
How to calculate Feed given Cutting Velocity, Tool Life, and Volume of Metal Removed using this online calculator? To use this online calculator for Feed given Cutting Velocity, Tool Life, and Volume of Metal Removed, enter Metal Removed Volume (vol), Life of Tool (TL), Cutting Velocity in Tool Life (V) & Cutting Depth (d'cut) and hit the calculate button. Here is how the Feed given Cutting Velocity, Tool Life, and Volume of Metal Removed calculation can be explained with given input values -> 700.0094 = 0.03412499/(4499.94*0.833333*0.013).
