TOLERANCE ANALYSIS CONSULTING

Varatech's dimensional control process is a thorough, logic driven series of steps whereby specifics are distilled from general Quality Build Objective information. Our dimensional control methodology provides a detailed sequence of activities that push quality upfront in the design cycle. This methodology ensures that assemblies go together 100% of the time and meet all predetermined performance objectives.

Our dimensional control engineers are experts in the following areas:

Design for assembly

GD&T/Functional datum structure

3D variation simulation modeling

Tolerance Stack-up Analysis

Functional gage and fixture design

Key steps for dimensional control:

Qualify and Quantify assembly's build objectives

Evaluate the geometric sensitivities of design concepts

Define and document locating schemes, datum structures, and GD&T

Gather and assess processing capability

Evaluate assembly process

Apply 3D simulation modeling to ascertain capability and system sensitivity

Use the existing functional GD&T to drive the development fixtures and gages.

Call out SPC and key characteristics

Produce and provide a quality process manual

Cost effective process maintenance using sensitivity study
