Overview

Dimensional inspection is sometimes referred to as dimensional measurement or dimensional metrology and is a specialized field encompassing a broad range of applications from large, complicated parts such as jet engine turbines to extremely small parts with tight tolerances that are part of life-saving medical devices. In manufacturing, this object might be a prototype for R&D or a custom-made component for a new production line or even a finished product. Simplified, dimensional inspection can be seen as the process for comparing what an object actually is to what it is supposed to be, and uses quantifiable values to measure virtually any physical characteristics such as:
  • Length, width, and height.
  • Angles and perpendicularity.
  • Roundness, flatness, and other geometric characteristics.
  • Position.
  • Shape profiles.
  • Surface characteristics.
  • Edge sharpness.
  • Thickness and uniformity.
Dimension Inspection

It’s critical to have viable and reliable means of accurately verifying your manufactured products and manufacturing processes. One of the primary ways to accomplish this is via an in-depth evaluation of the first piece from your production run — also called first article inspection. We take great care in comparing the actual condition of manufactured parts, components, tooling and dies to the nominal condition as expressed in 2D drawings, 3D Models,

Applications

Methodologies

In general, when dimensional measurement is required, the results must be both accurate and precise. Although multiple techniques and countless applications exist, there are four main categories of dimensional inspection.

First Article Inspection:

Implementing a manufacturing process requires extreme attention to detail, especially if the process is new or if the equipment has been specially designed. First article inspection is required to ensure that the equipment was properly installed and calibrated, and to verify the manufacturing process. Dimensional measurement is used to compare the first objects from the manufacturing line to 3D CAD models, engineering drawings with tolerances, and/or other specifications.

Quality Control:

When objects coming off a manufacturing line must meet certain quality standards, measurement equipment is used to confirm that the dimensions fall within the required tolerance levels. In some cases, when the tolerance levels are more rigorous, each object is measured automatically. In other cases, batches might be spot-checked for quality.

Regulatory Compliance:

In industries for which regulatory compliance is necessary, dimensional measurement ensures that the required specifications are met. Regulatory bodies such as the FDA or FAA often have requirements regarding the dimensions of certain components.

High-Precision Engineering:

When creating a larger assembly from smaller parts, high precision is often required. If a minor flaw or inconsistency can impact an entire process, ensuring that such imperfections do not exist is critical.

The entire purpose of manufacturing is to create a process that is repeatable, scalable, and reliable. When successful, it results in lower production costs and lower pricing for the end user. However, precise, accurate measurements are required for any manufacturing line to be successful.

Dimensional inspection during the production process can help prevent costly errors such as:

  • Flawed Batches: A production line that creates duplicate products requires precision setup and alignment. Errors in the production line can lead to entire batches of flawed goods, which can be quite expensive in both time and cost to correct the production error. Dimensional measurement is worth the investment to prevent these expensive mistakes.
  • Defective parts: Using dimensional inspection as part of the quality control process for high-precision manufacturing ensures that each part meets the required specifications.

Quality control is essential for producing consistent products, but implementing dimensional measurement even earlier in the process can help prevent costly manufacturing errors that can lead to problems.

Dimensional inspection is a big part of the manufacturing, and the end product of the process could be a finished product, a custom design component, and an R&D prototype. For the measurement of the equipment, dimensional inspection makes use of different values such as: The width, length or height.

A dimensional inspection report is an easy to read summary of the inspection. It will include a print with ballooned dimensions. This is usually a circled or squared number adjacent to each print dimension. The balloons should include each case of a multiple instance dimension referenced. So, a pattern of 5 holes will have a ballooned number for each of the five holes.
An image of the inspection set up with your part should be clearly shown to allow any repeat or future measurements. We find that having this included in the report answers many questions and improves the overall communication.

Accurate inspection dimensions are critical to the Manufacturing Engineer (ME). A large part of an ME’s job is to troubleshoot and correct issues that occur during manufacturing. Knowing the root cause of the problem is key to implementing a long-term solution and not having to fight the same issue again and again. Accurate and reliable dimensional information on the parts is critical to understand the baseline conditions. Use Think3D expertise to help satisfy these measurement needs.
