MICRO MACHINING: PLAN SMALL FEATURES AND PROVE THE RESULT
Editable planning/verification record — Yenra
Updated: October 2, 2026
Article: https://yenra.com/micro-machining/

Purpose: Prepare a feature-level feasibility and inspection brief that a machining supplier can evaluate.
Intended reader: Designers, precision job shops, and manufacturing engineers

HOW TO USE
Save a working copy. Enter the actual specification, units, assumptions and evidence references in each field. Preserve original observations and record changes. Have the responsible reviewer resolve missing or conflicting requirements before release. Examples below are fictional teaching inputs, not process settings or acceptance standards.

RECORD
1. Drawing revision, material/condition, quantity and feature function:
   ____________________________________________________________

2. Feature size/depth/aspect ratio/radius, units, tolerance and datum:
   ____________________________________________________________

3. Process candidates and tool/electrode/wire access:
   ____________________________________________________________

4. Workholding, release state, cleaning and burr requirements:
   ____________________________________________________________

5. Measurement definition: location/depth, method, datum, sampling:
   ____________________________________________________________

6. Calibration, uncertainty/coverage basis and agreed decision rule:
   ____________________________________________________________

7. Representative trial route, individual measurements and rejected features:
   ____________________________________________________________

8. Tool wear/change criteria and response to drift:
   ____________________________________________________________

9. Supplier/customer review and approved production route:
   ____________________________________________________________


WORKED EXAMPLE AND LIMITS
Fictional slot: 0.200 +/- 0.005 mm gives 0.195 to 0.205 mm (195 to 205 micrometers). Measured 0.204 +/- 0.002 mm expanded uncertainty gives 0.202 to 0.206 mm. Apply the agreed decision rule; this example does not declare acceptance.
