CalcIng Engineering
ChatGPT pluginMachine element calculations
CalcIng Engineering connects ChatGPT to the calculation apps of saas.calcing.de. The model calls the apps as tools: find the right app, read its input schema, check the inputs, calculate, and return the app's result with its notes, warnings and provenance (app, version). The numbers come from the calcing apps on our server, the same apps as in the calcing user interface; the model does not estimate results itself, and a failed calculation is reported, not replaced.
Included: shafts and axles, key connections, interference fits, ISO fits, bolted joints, rolling bearings (rating life and contact analysis), shaft-bearing systems, rolling contacts, planetary gears, strength assessment with the local and the nominal stress concept, district-heating branches, axial fans, horizontal- and vertical-axis wind turbines, plus material lookup and handing a result over as the input of the next app.
Intended for mechanical engineers and designers. Sign in with your calcing account (OAuth) for complete results. Without sign-in, calculations return a shortened answer: main results, overall assessment, warnings and notes. The calcing terms of service, section 10, govern access and use. Results must be checked professionally before use. A connection can be revoked at any time in calcing under "API & Skills".

Example prompts
- “Bearing 6206 (C = 21.4 kN, C0 = 11.3 kN), radial 5 kN at 1500 rpm, reliability 90 %: how long does it last?”
- “Which machine element calculations can calcing run, and what inputs does the bolted joint app need?”
- “Check a shaft shoulder to DIN 743: which inputs and which material from the app database do you need?”
Skills
engineering-calculation
Run a mechanical engineering calculation with the calcing tools of this plugin (saas.calcing.de). Use when the user asks to size, check or verify a machine element or component - shaft or axle strength, parallel key, interference fit, ISO fit/tolerance, bolted joint, rolling bearing life or contact, shaft-bearing system, rolling contact (Hertz), planetary gear stage, FKM strength assessment, district-heating branch, axial fan, horizontal- or vertical-axis wind turbine - or to look up a material for such a calculation.
result-handoff
Pass the result of one calcing calculation on as the input of another calcing app (saas.calcing.de tools of this plugin). Use when the user wants a follow-up calculation from a result they just got, for example "now check the key on this shaft" or "use this bearing result in the next step".
