Engineering Drawing & GD&T
ASME Y14.5 — GD&T
The dimensioning and tolerancing standard we interpret on your drawings.
ASME Y14.100 — Drawing Practices
Engineering drawing format, views, and notation conventions.
Title Block & Revision Control
What we look for: part number, revision, material callout, finish, tolerances.
Accepted File Formats
SolidWorks, Parasolid, .STEP, .IGES, .DXF, and .PDF drawings.
Tolerances & Fits
Standard Tolerance Bands
Typical: ±0.005", precision ±0.001", tight ±0.0005"–±0.0002".
ANSI/ASME B4.1 — Limits & Fits
Clearance, transition, and interference fit classes for mating parts.
True Position & Datums
How we hold hole patterns and features to datum references.
Flatness / Parallelism / Squareness
Form controls we achieve by machining faces in a single setup.
Materials
Aluminum (6061, 7075, 2024)
Common alloys, tempers, and where each is best applied.
Stainless (303, 304, 316, 17-4)
Corrosion resistance and machinability trade-offs.
Titanium (Grade 2, Grade 5 / 6Al-4V)
High strength-to-weight for aerospace and medical.
Engineering Plastics (Delrin, PEEK, UHMW)
Low-friction, chemical- and heat-resistant polymers.
Surface Finish & Coatings
Ra Surface Roughness
Typical as-machined 63–125 µin; finer with secondary operations.
Anodizing (Type II / Type III)
Clear or black, decorative or hard-coat for wear resistance.
Passivation (ASTM A967)
Restores corrosion resistance on stainless parts.
Bead Blast / Powder Coat / Polish
Cosmetic and functional finishing options.
Threads & Features
Unified (UNC/UNF) & Metric (ISO)
Standard and custom thread sizes, tapped or single-point.
Thread Class of Fit (2B / 3B)
How we control thread tolerance for assembly.
Counterbores & Countersinks
Standard cap-screw and flat-head callouts.
Slots, Keyways & Bolt Circles
Common features — sketch them in our Design Studio.
Quality & Inspection
ISO 9001:2015 (NSF-ISR)
Our certified quality management system.
First Article Inspection (AS9102)
Full dimensional verification on first production parts.
CMM & Optical Comparator Reports
Starrett, Helmel, and Mitutoyo metrology equipment.
Ring & Plug Thread Gaging
Go/no-go verification of threaded features.
