Reverse Engineering Inspection and its use

The quality control and inspection process in reverse engineering usually take three steps to determine if the 3D CAD model of the part is available or not. Those three steps are as follows:

  • The first step involves scanning the part and generating a computer model's point cloud format.
  • The second step involves merging and aligning the two computer models (CAD and Scanned one) to validate the part's specifications.
  • The final step, i.e., step three, includes visual computer model inspections and alignment of the merged models for any deviations in the geometry and dimensions.

The quality control outcome would be some recommendations for corrections, so the part meets perfectly with the blueprint specifications before the part's mass production.

Following are some uses of Reverse engineering inspection: 

  • Reverse engineering inspection comes in handy while carrying out Zero Article Inspection or ZAI. Zero article inspection is a type of workflow where the upcoming physical part doesn't follow the master design model but rather a derivative of the master model due to fluctuations in dimensions and tolerances. The review of the last digital representation before downstream purposes is known as zero article inspection. In this case, reverse engineering inspection provides sufficient information, allowing the inspector to check tolerances, dimensions, and any other information relevant to such projects. It gives assurance and confidence to produce quality components.
  • Reverse engineering inspection is an essential inspection of stylized parts/surfaces - where just dimensional inspection is not enough.
  • Reverse engineering inspection is an essential player during First Article Inspection (FAI). During the part manufacturing process, when an issue is detected with the manufactured part, the notification of the same has to go back to its design. The purpose is to keep the 3D CAD model in sync with the actual piece as manufactured. The hybridization of reverse engineering and inspection makes such updates easy to convey and apply, plus keeps the feedback circle opens across departments.
  • Reverse engineering inspection has found significant use in the additive manufacturing industry. Such a process helps bring down process-generated errors while calibrating & modifying building criteria to cut down the process itself's influence.

Vision Based Inspection

With the remarkable growth in the demand for goods due to consumerism over the recent years, there has been an overwhelming production in the industry. A higher production speed demands a higher number of inspection checks and quality assurance. This is where the vision-based inspection system plays a significant role. The tendency in manufacturing industry these days is to migrate from the usual manual testing method to a vision-based inspection system. This is to ensure overall quality and obtaining high standards.

What Vision-Based Inspection System can do

Vision-based inspection systems, also known as machine vision systems, provides automated image-based inspection for a diverse industrial and manufacturing applications. 

Two-dimensional (2D) and three-dimensional (3D) machine vision systems are now commonly used for robot guidance, automated inspection, quality control, sorting, and much more. 

Vision-based inspection systems come furnished with a camera or multiple cameras, and even video and lighting, which makes them capable of measuring parts, verifying correct positioning of components, and recognizing part shapes and patterns.  Vision systems are capable of measuring and sorting pieces at high speeds.  Computer software processes images captured during the assession of data. The vision system is intelligent enough to –

Provide inputs that impact the function one is trying to assess, often triggering an operator to act,

be embedded in your system to provide a constant stream of information.

Applications of Vision-Based Inspection System

The vision-based inspection system plays a role in industries where quality control is necessary.  Some essential aspects of the vision inspection system are as follows:

  • Assisting robotic systems in acquiring the positioning of parts. It helps in further automation and streamlining the manufacturing process. 
  • The vision system collects data and helps improving efficiency in manufacturing lines, sorting, packing, and other applications. 
  • The information obtained by the vision-based inspection system can help identify problems with the manufacturing line or other functions to improve efficiency, stop inefficient or ineffective processes, and identify unacceptable products.
Industries using Vision-Based Inspection System

Depending upon the type of industry, production, and usage, vision-based inspection systems can be customized to meet the needs of many industries.  As a result, many companies enjoy the use of this technology for quality control and even security purposes.  Industries using vision inspection systems include:

  • Automation
  • robotics
  • pharmaceuticals,
  • packaging,
  • automotive,
  • food and beverage,
  • semiconductors,
  • life sciences,
  • medical imaging,
  • electronics,
  • consumer goods

The advantages of vision-based inspection systems include, but are not limited to, production improvements, increased uptime, and reduction in expenses.  Vision systems allow companies to conduct 100% inspection of parts for quality control purposes.  Hence, it ensures that all products will meet the customers’ specifications.  If you want to improve the quality and efficiency of your industry, a vision inspection system could be the answer for you.
