Precision Made Easy: meviy Introduces Angular Dimension & Tolerance Support for Milled Parts

Modern manufacturing increasingly demands precision on every detail, not only for linear dimensions but also for the exact angles between component surfaces. For engineers working on parts with inclined planes, sloped fixtures, or angled mating surfaces, the ability to define and control angular tolerances is crucial. Until now, this capability was missing from meviy’s automated quotation workflow, which meant such parts often required manual review and therefore delayed the quoting process.


With the latest update, meviy now allows users to specify angular dimensions and tolerances directly in the 3D viewer. This makes it possible to obtain automated quotations for many high-precision milled parts that were previously unquotable.

Technical Overview of meviy’s Angular Dimension & Tolerance Update

 

With this release, engineers can:

 

  • Select two surfaces in the 3D viewer
  • Place an angular dimension
  • Input a tolerance directly in the dimension settings dialog

 

Key Technical Details:

 

  • Automatic Quotation (AQ) tolerance range: 0.16° to 10°
  • High-precision capability: down to ±0.08° (0.02°–0.16° falls under Manual Quotation, MQ)
  • Lead time: Unchanged, regardless of tolerance setting
  • Configurable defaults: Set preferred tolerances in user settings
  • Inspection methods: Angle gauges for standard cases, CMMs for complex geometries

 

Limitations:

 

  • Not applicable to chamfers smaller than C15
  • Not for surfaces under 9 mm²
  • Not for curved/rounded surfaces or radii
  • Not for surfaces where neither is parallel to a principal plane (XY, YZ, XZ)

What Are Angular Dimensions and Angular Tolerances in Machining?

 

In precision machining, angular dimensions define the exact inclination between two surfaces, while angular tolerances set the permissible deviation from that intended angle. They ensure that angled features meet strict functional, assembly, and performance requirements.

 

For example, a clamping jig may need a 15° sloped face with only ±0.1° deviation to hold workpieces securely, or a transport guide might require a specific incline to ensure consistent flow direction. Without the right angular tolerance, even a minor deviation can cause misalignment, vibration, or reduced efficiency.

Advantages of Defining Angular Tolerances in the Design Stage:

 

  • Enhanced Fit and Functionality which prevents assembly misalignment and performance issues.
  • Reduced Post-Machining Adjustments which saves cost and time by achieving precision during machining.
  • Improved Reliability that ensures consistent part performance over its service life.
  • Faster Production Start because integration into automated quoting eliminates delays.

Relevant Applications and Industries for Angular Dimensions & Tolerances

 

Manufacturing Fixtures and Tooling

 

  • Clamping jigs with angled fixtures.
  • Inspection jigs for precise alignment.

 

Mechanical Assemblies

 

  • Mating shaft or plate surfaces with angular alignment.
  • Directional guides in transport machinery.

 

Aerospace and Automotive

 

  • Angled joints for structural or aerodynamic performance.

 

Electronics and Automation

 

  • Compact enclosures with angled internal surfaces.

 

Summary

 

The addition of angular dimension and tolerance support marks a significant step for meviy in expanding its automated quotation capabilities. Engineers can now design inclined surfaces with tolerances down to ±0.08° and move seamlessly from CAD upload to production without any additional lead time.

 

Automation now delivers angular accuracy directly in your digital quote.
