INDUNECT / ENGINEERING TOOLSWORKSPACE INDEX
Engineering calculations.
With context.
Purpose-built calculators for real mechanical and industrial work. Inputs, assumptions, methods and limitations stay visible so the result can be reviewed—not merely accepted.
START WITH THE ENGINEERING QUESTION
Choose a workspace.
Indunect tools are released progressively. Beta workspaces remain explicitly preliminary—not substitutes for applicable standards, project-specific verification or engineering approval.
Cyclone design workspace
Workbook-verified cyclone sizing, geometry comparison, grade efficiency, pressure-drop methods, duct-network head loss and fan-power sizing in one transparent engineering workspace.
Air-slide conveyor sizing
Check preliminary conveying capacity and clear width, aeration, pressure losses, air-density-corrected blower duty, manifold sizing and motor rating with a printable calculation report.
Silo flow-pattern screening
Screen hopper geometry and outlet size against test-derived mass-flow and arching limits, while documenting the bulk-solids data still required for a defensible design.
Conveyor pulley shaft sizing
Size or check a symmetrical drive or non-drive pulley shaft from belt forces using a CEMA 7th-edition stress reference and a configurable bearing-slope limit.
Gear & shaft design workspace
Explore preliminary 20° spur-gear geometry, parallel-shaft gearbox ratios and idealized shaft stress, deflection and speed checks with SI/imperial units.
Bearing life & selection check
Check variable-duty equivalent bearing load, ISO 281-style rating life, target dynamic rating and static safety with explicit catalogue factors and a printable calculation report.
Hub, key & shaft connection
Check a single parallel-key torque connection for key shear, bearing pressure, required effective length, torque capacity, nominal shaft torsion and hub/keyway geometry.
Machining parameters & time
Calculate spindle speed, feed, material-removal rate, idealized machining time and optional cutting-power demand for milling, turning and drilling.
Threads, drilling & CNC cycles
Plan thread lead and synchronized tapping feed, drilling speed/feed, peck-cycle motion and idealized hole-cycle time with SINUMERIK cycle-family orientation.
Fits, tolerances & inspection
Calculate explicit hole/shaft limits, clearance/interference range, linear worst-case/RSS tolerance stacks and uncertainty-aware dimensional inspection intervals.
A GROWING ENGINEERING LIBRARY
Built around industrial work.
Dedusting & Air
Cyclones, ducting, filtration, pressure drop, airflow and dust-control calculations.
1 beta workspace →02Bulk Materials
Air slides, conveyors, storage, flow behaviour and material-handling checks.
3 beta workspaces →03Machine Design
Gears, shafts, bearings, fits and practical preliminary design workspaces.
3 beta workspaces →04CNC & Manufacturing
Machining calculations, CNC references and manufacturability-oriented engineering tools.
3 beta workspaces →NOT A BLACK BOX
A number is only useful when you can defend it.
Each Indunect calculator is designed to expose the engineering path behind the output: what you entered, what was assumed, which method was applied, and where professional judgement is still required.
