Precision where it matters: meviy expands tolerance capability for CNC milled parts

In practical assembly work, tolerance control often determines whether a design functions as intended. When parts must align, locate, or mount precisely, tolerance limits define whether assembly runs smoothly or requires adjustment and rework.

 

The latest release from meviy expands machining precision exactly where assemblies require it—while preserving the familiar digital workflow engineers rely on.

 

This update is a precision upgrade focused on functional performance.

What engineers struggle with

 

If you work with functional assemblies, you already know the pattern:

 

  • A tolerance of ±0.05 mm is often too loose for parts that must align.
  • Even ±0.02 mm can create misalignment, stack-up issues, or inconsistent fits.
  • Specifying ±0.01 mm traditionally triggers drawings, emails, and manual quotation requests.

 

The result is compromise.

 

Engineers either loosen tolerances to stay within automated processes—or accept slower workflows and fragmented communication to achieve production-level precision.

 

 Neither option supports efficient production.

What this launch changes

 

This release removes much of that friction.

 

meviy now supports tighter machining tolerances, expanding the achievable range to:

 

  • External dimensions: from ±0.05 to ±0.01
  • Hole-to-hole dimensions: from ±0.02 to ±0.01

 

In practice, this allows engineers to order assembly-critical parts through meviy while specifying tighter tolerances where required. 

 

That means production-level precision, without slowing engineers down.

More than prototypes: supporting functional assemblies

 

This upgrade reinforces meviy’s position as a platform built not just for fast prototypes, but for functional and assembly-critical components.

 

With ±0.01 support:

 

  • Mounting interfaces can be designed for consistent alignment.
  • Hole patterns can maintain positional accuracy across assemblies.
  • Tolerance stack-up can be better controlled at the design stage.

 

And you don’t have to abandon digital automation to achieve it.

 

The boundary between automatic and manual quotes remains clear and transparent. Where tighter tolerances are technically feasible, they are supported. Where they are not, the system maintains realistic expectations.

 

That clarity is essential for engineers working under production deadlines.

 

Where this matters most

 

The impact of tighter tolerances becomes obvious in precision-driven industries:

Automotive and E-Mobility

 

Jigs, fixtures, brackets, and sensor mounts where positional accuracy directly affects performance.

Industrial Machinery

 

Mounting plates, alignment parts, and interfaces where cumulative tolerance stack-up can disrupt entire systems.

Automation and Robotics

 

End-effectors, sensor holders, and compact assemblies requiring precise alignment and repeatability.

Electronics and Semiconductor Equipment

 

Fixtures and mounts for PCBs, optics, and inspection systems where even small deviations matter.

Medical and Laboratory Equipment

 

Mechanical interfaces demanding consistent, repeatable positioning.

Aerospace and Defence (Non-Flight Parts)

 

Tooling, test equipment, and ground-support components requiring tight dimensional control.

In all these cases, ±0.01 is not about perfectionism—it is about functionality.

 

Ready to design with greater precision?

 

If your assemblies require tighter fits, more reliable alignment, or improved positional accuracy, you no longer need to compromise between speed and precision.

 

 Upload your CAD model and specify ±0.01 where required. Parts transition to manual quote where technically feasible.


The digital workflow remains structured and traceable.

FAQ

Why is ±0.01 handled through manual quote?

 

Tolerances at ±0.01 require careful evaluation of geometry, material, and manufacturing feasibility. Manual quote ensures that tighter tolerances are applied appropriately and realistically, while still preserving meviy’s digital workflow.

Will selecting ±0.01 cause the system to fail?

 

No. With this release, specifying ±0.01 no longer disrupts the quoting process. Instead, eligible parts transition smoothly into manual quote evaluation without unnecessary friction.

Are all geometries eligible for ±0.01?

 

Not automatically. The tighter tolerance range is supported where geometry allows. Factors such as part size, material, feature type, and manufacturing constraints will determine feasibility under manual quote.

Is this suitable for production parts?

 

Yes. This release specifically supports functional and assembly-critical components, making meviy more suitable for low-to-medium volume production and precision-driven applications.
