Metalworking calculators

Enter the divisions or angle, worm ratio, and index plate set to get a crank-and-hole setting. The result calls out exact simple indexing, exact compound indexing, or the nearest available simple setting with error.

Enter the finished outside diameter, knurl pitch, pattern, and wheel data to find the nearest trackable turned blank. The result shows the predicted finished diameter, signed error, tooth count, and adjacent choices.

Enter the leadscrew, target thread, and the change gears you actually have. The calculator ranks simple and compound trains by pitch error and shows how much the lead will drift.

Enter the finished end diameters and taper length to set a compound, plan a tailstock offset, and check a diameter partway along the work.

Enter the finished spun shape and sheet thickness to estimate the equal-area blank diameter. The result adds trim stock, weight, scrap, and a simple machine-swing clearance check.

Enter the material, bend length, V opening, forming method, and ratings to estimate forming force and check both the press brake and tooling limits.

Enter peak and background current, voltage, duty cycle, pulse frequency, travel speed, and efficiency to estimate pulsed welding arc energy and heat input. The result also shows the travel speed that would meet a maximum heat-input target with the same waveform settings.

Measure a formed test coupon and use its flat length, outside legs, inside radius, and bend angle to solve the K-factor that fits that bend. The result also shows the bend deduction and allowance behind the answer.

Enter the weld geometry, total length, filler metal, and process to estimate deposited weld metal and the filler to buy. The result rounds purchasing up to whole packages and keeps the material allowance visible.
