Fabrication & Workshop calculators
Choose a task below. Check each calculator’s assumptions and units before using its result.
Sheet Imposition Calculator - Gang Run Layout & Up Count
Determine maximum number of finished pieces per press sheet ("Number Up"), optimize regular vs rotated imposition, and calculate paper yield efficiency.
Sheet Metal Blanking Punch & Die Clearance Calculator
Calculate per-side die clearance, cutting & stripping force tonnages, tooling sizing rules for blanking vs piercing, and anticipated burr height.
Sheet Metal Blanking Tonnage & Piercing Force Calculator
Calculate stamping press tonnage ($F = P \cdot t \cdot \tau$), die shear angle force reductions, stripping force, and machine capacity safety margins.
Shrink-Fit Toolholder Calculator - Heat & Grip Torque
Determine required induction heating temperatures to achieve insertion clearance, calculate Lamé radial clamping pressure, and evaluate maximum slip torque transmission.
Surface Grinding Downfeed, Crossfeed & Sparkout Passes
Calculate downfeed per pass ($a_p$), crossfeed stepover, table longitudinal traverse speed, spark-out passes, and Ra surface finish for toolroom grinding.
Thread Milling Helical Feed Compensation Calculator
Compensate CNC centerline feed rates ($F_{center}$) for internal and external helical thread milling to maintain true peripheral chip load ($f_z$) and prevent cutter breakage.
Thread Whirling Head Tilt & Feed Calculator
Calculate precise whirling unit tilt angles, synchronized workpiece C-axis RPM, axial feed rates, and single-pass cycle times for Swiss CNC turning.
Welding Rod Calculator - Filler Metal Weight & Lbs
Determine deposited weld metal weight, electrode stub loss, and total filler metal pounds to order for structural and pipe welds.
Wire EDM Cutting Speed & Kerf Offset Calculator
Calculate total spark kerf offsets, volumetric cutting speeds, multi-pass skim cut step-overs, wire lag deflection, and minimum internal corner radius limits.
Woodworking Dovetail Joint Angle & Spacing Calculator
Calculate precise pin and tail spacing, traditional 1:6 (softwood) and 1:8 (hardwood) slope angles, and socket depths for hand-cut dovetails.
