CAD/CAM ENGINEERING LABORATORY

CAD/CAM: Complete Engineering Capability

10 discipline modules covering parametric modelling, drawings, CNC, FEA, and design-for-manufacturing.

Parametric Solid Modelling

History-based parametric CAD using SolidWorks (primary), Creo Parametric, CATIA V5/V6, and Autodesk Inventor. Design intent is captured in feature trees with driving dimensions — any change propagates automatically through parts, assemblies, and drawings.

Primary toolSolidWorks 2025 Premium

Also proficientCATIA V5 / Creo 10 / NX

Part modellingFeature-based, fully parametric

Surface modellingClass-A (SW Surfacing)

PDMSolidWorks PDM Professional

File formatsSTEP, IGES, Parasolid, STL, DWG

Design tables in SolidWorks automate family-of-parts — one master model drives 50+ variants (bolt sizes, flange ratings) from an Excel table. Configuration management ensures zero revision errors across 1000+ part assemblies.

GD&T Engineering Drawings

ASME Y14.5-2018 and ISO 1101 compliant GD&T drawings. All drawings include: title block, revision table, BOM, surface finish calls, material specification, heat treatment notes, and first/third angle projection. Tolerance analysis using 1D and Monte Carlo methods.

Sheet Metal Design & Flat Pattern

SolidWorks sheet metal features: base flange, edge flange, miter flange, hem, lofted bend, and forming tools. K-factor calculation for accurate flat pattern development. DXF export direct to laser/plasma/waterjet cutting machines. Supported materials: mild steel, SS, Al, brass, copper.

Gauge range0.5 mm – 12 mm

K-factor range0.30–0.50 (material dep.)

Bend allowanceBA = (π/180)×(r+K×t)×θ

Min bend radius1× material thickness

Flat DXF exportDirect to laser cutter

Forming toolsLance, louver, PEM standoff

K-FACTOR CALCULATION

Material: SS 304 (1.5 mm)
K-factor = 0.38 (from DIN 6935)
Bend angle θ = 90°
Inside radius r = 2.0 mm
BA = (π/2) × (2.0 + 0.38×1.5) = 3.97 mm
Flat length = L1 + L2 + BA
= 50 + 75 + 3.97 = 128.97 mm
Tolerance: ±0.2 mm on flat

Weldment & Structural Design

SolidWorks Weldments module for structural steel frames using standard profiles (IS 808, AISC): I-beams, C-channels, angles, RHS, SHS, pipes. Auto-generation of cut list with lengths, mitre angles, and coping. Weld symbol annotation per AWS A2.4 and ISO 2553.

Profile standardsIS 808 / AISC / DIN 1025

Weld symbolsAWS A2.4 / ISO 2553

Structural analysisSolidWorks Simulation / ANSYS

Weld typesFillet, butt, groove, plug

Cut listAuto-generated BOM with mitre

Design codeIS 800 / AISC 360 / Eurocode 3

FILLET WELD STRENGTH CALC

Throat thickness: a = 0.707 × leg size
Leg size = 8 mm → a = 5.66 mm
Weld length: L = 150 mm
Weld area: Aw = a × L = 849 mm²
Allowable shear: fw = 0.4 × fu = 0.4 × 410 = 164 MPa
Capacity = fw × Aw = 164 × 849 = 139 kN
Applied load: 85 kN → SF = 1.64 ✔

FEA Simulation — SolidWorks & ANSYS

Static stress, fatigue (S-N curve, Miner's rule), buckling, thermal, frequency, and drop-test simulations. SolidWorks Simulation Premium (integrated) for quick design iteration; ANSYS Mechanical for complex nonlinear and contact problems. Result: optimised designs, not guesses.

Design for Manufacturing & Assembly (DFM/DFMA)

DFM review ensures every feature is manufacturable at the specified tolerance. Common DFM violations caught: blind holes requiring special tools, undercuts in moulded parts, thin walls below casting limits, tolerance stack-ups exceeding gauge capability. DFMA reduces part count and assembly time.

⚠ DFM Machining

Check: minimum tool access, minimum bore depth/dia ratio (<4:1), internal corner radii ≥ 1/3 tool dia, no features requiring re-setup on 3-axis machine.

⚠ DFM Casting

Draft angles ≥ 2°, uniform wall thickness ±20%, fillet radii ≥ 2mm, no sharp internal corners (stress risers), gate/riser locations planned during CAD.

⚠ DFMA Assembly

Boothroyd-Dewhurst DFA: minimum part count, self-aligning features, single insertion direction, standard fasteners only, error-proof assembly (poka-yoke geometry).

Large Assembly Management

Managing SolidWorks assemblies of 500–5000+ components without performance degradation. Techniques: SpeedPak, simplified configurations, multi-body parts, split-file approach, and large assembly mode. BOM generation, interference detection, and motion analysis.
