What's inside the Machine Design — The CADfinity Edge
Most machine design courses are software button tours. This page summarises the free guide: the three layers a real machine designer needs — engineering theory, design for manufacturing, and production reality — and how the CADfinity diploma is built around one defended capstone instead of disconnected exercises.
The three layers of real machine design
Modelling skill is the smallest part of the job. A designer is judged on whether the machine works, can be made, and can be made at a sensible price.
- Theory — loads, stress, fatigue, bearings, shafts, fasteners, power transmission
- DFM — tolerances, fits, machining and welding realities, standard parts over custom ones
- Production reality — drawings a shop can quote from, lead times, inspection and cost
What tightening a tolerance really costs
Moving a fit from a general machining tolerance to a ground tolerance can multiply the cost of a feature several times over. The guide includes a cheat sheet mapping typical fits to process, surface finish and relative cost so design decisions are made with the invoice in mind.
The seven-stage diploma map
Stages run from engineering fundamentals through component selection, assembly design, tolerance and fits, drawings and GD&T, cost and manufacturing review, and finally a capstone machine that is defended in front of reviewers.
A drawing review checklist
Before any drawing leaves the office it is checked against a fixed list: datums that reflect assembly, tolerances that are functional rather than habitual, surface finish only where needed, standard parts called out by supplier code, and a title block that lets a shop quote without a phone call.
Common questions
What is the difference between CAD training and machine design training?
CAD training teaches software features. Machine design training teaches you to size components, choose fits, design for the manufacturing process available, and produce drawings a workshop can build and inspect from.
Do I need to know SOLIDWORKS before a machine design diploma?
Basic part and assembly modelling is enough. The diploma is about engineering decisions; the software is the tool used to record them.
What is a capstone project in machine design?
A complete machine or sub-assembly designed from a specification, including calculations, component selection, full drawing set with GD&T and a cost review, then defended in a design review.
