Closed Loop Manufacturing - Perceived Quality & Tolerance Objectives

Take advantage of variation analysis and high-end visualization to determine the impact of design specifications on your product's appearance. 

What is Perceived Quality? 


Perceived Quality is the quality attributed to a product based on its perceptual experience. This incorporates the experience a customer has with a product and how it makes them feel about the product. Bringing together the shape, the appearance, the texture and physical feel of the product as well as the emotional experience of using the product, Perceived Quality directly affects the customer’s opinion of the value of the product. This perceived value then drives the business.

Closed Loop Manufacturing in the Product Lifecycle

Closed Loop Manufacturing supports your Product Lifecycle by creating information feedback loops, and connecting systems and departments within your organization to make your process more efficient and effective. 


The Product Lifecycle shown focuses on a CAD driven process. Beginning with GD&T and CAD model development, the process continues into manufacturing with the creation of inspection plans, collection of inspection data and SPC reports from the collected information.

Product Lifecycle Process

  1. Perceived Quality Studies 
  2. GD&T Plans and Drawings 
  3. CAD Model Creation
  4. Inspection and CMM Plans Creation
  5. Inspect and Measure in Production
  6. SPC Reports 
  7. Root-Cause Analysis - Non-Conformance Resolution
  8. Monitor Production 


By using Spec Studies, Perceived Quality Studies in 3DCS, design specification limits can be decided based on the appearance of those tolerances on gap and flush conditions. These can be used during the CAD design as a starting specification limit that can then be refined by manufacturing engineering to create a set of specifications that are both sound engineering and will produce an attractive product that showcases its high quality production. 

Spec Studies can be used with any CAD system and 3DCS Variation Analyst, but they are especially useful in the 3DEXPERIENCE, where live-rendering combines with your Spec Studies to give you incredible images of your product with manufacturing variation or set gap and flush conditions.

Engineering Talk - DCS's Blog on Quality and Engineering

Engineering Talk's focus is on discussing topics in dimensional and manufacturing quality to help inform professionals about current trends and technologies that are quickly becoming adopted in industry to combat common causes of manufacturing costs - scrap, rework. In addition, you'll find details about all of DCS's activities from webinars, events, articles, and software releases.
