Advanced Metalcutting Calculators
contains four calculators for major metalcutting operations: Milling
; and a fifth for calculating exact Machining Time
when facing, cutting off, and deep grooving. All calculators are developed in Microsoft Excel and execute all parameters in both U.S. and metric units. These calculators provide computations more accurate than any other calculators on the market and can be used by anyone involved in manufacturing, including machinists, technicians, and engineers.
Power requirements when milling, turning, boring, or drilling are calculated by tangential force and cutting speed, or by torque and the number of revolutions per minute. These requirements are calculated when cutting inserts are sharp and prior to indexing or changing them
- Cutting force versus ultimate tensile strength of the work material and area of the chip.
- Torque at spindle versus cutting force and the cutter diameter.
- Adjustments to feed rate depending on the cutter geometry and width of cut
- Cutting force components tangential force versus depth of cut, feed rate, and the work materials power constant; feed and radial forces versus tangential force and the coefficients of proportionality, depending on the group of work materials.
- Torque at spindle versus tangential force and the workpiece diameter
BORING CALCULATOR (in addition to the same two features immediately above)
- Deflection versus resulting cutting force, unsupported length of the boring bar, moment of inertia of the bar cross-sectional area, and the modulus of elasticity of the bar material. Note: The method of determining feed and radial forces when turning and boring, and the calculators that utilize this method are patented (US Patent # 6,836,697)
- Tangential force versus drill diameter, feed rate, power constant of the work material, and the drill wear factor.
- Thrust (axial force) versus tangential force and the coefficient of proportionality establishing thrust-to-tangential force ratio.
- Torque at the drill versus tangential force and the drill diameter.
- Radius of the workpiece when the machine tool spindle runs at the maximum rpm.
- Machining time (in minutes) when facing or cutting off to the center of the workpiece; or when deep grooving, facing, or cutting off to a shoulder of the workpiece.
Advanced Metalcutting Calculators contains four calculators, each for major metalcutting operations: Milling, Turning, Boring, Drilling, and one calculator for exact machining time when facing, cutting off, and deep grooving. All calculators are developed in Microsoft Excel, and execute all parameters in both U.S. and Metric units of measure. These calculators provide more accurate computations than and other calculators on the market. They are unique in computing cutting forces, torque values, and required machining power. Additionally, feed and radial cutting forces are calculated by the Turning and Boring Calculator (covered by U.S. Patent No. 6,836,697). Any metalworking professional is sure to find these calculators handy, especially for maximizing productivity of cutting by selecting such parameters at which nominal power of the machine tools can be effectively utilized.
