Selecting the Right Vision Measuring System

 There are seven things to consider when selecting the right vision measuring system for your application:

 


Part Weight

 

Since vision measuring systems require a working phase of the glass so that light can pass through, there is a limit on the weight of the part that these systems can handle. While smaller systems can easily handle up to 15kgs, larger systems can take up to 30Kgs. For weights over that limit, the Coordinate Measuring Machine (CMM) is the best option.

 

Part Size

 

The portion size determines the XYZ measuring range of the system. Check the largest part you want to measure and specify the required measurement range for each axis accordingly.

 

Feature Size

 

The dimensions of the features on the part will dictate the optical magnification, screen size, and resolution of the scale. Specify the dimension of the smallest feature you want to measure and the provider will suggest the most suitable configuration for you.

 

Feature accessibility

 

Are the features that need to be measured, in the line of sight on the z-axis. If yes, then the CCD camera installed on the Z-axis can access all the features visually. However, if some features are not in the line of sight, an additional tactile probe will be needed to access and measure them.

 

Feature number

 

The number of features that need to be measured in a part and the time taken to measure them decide whether a motorized work stage with CNC controls and joystick controls is needed. Automatic control allows the programming of measurement steps so that the system can automatically measure for equal parts.

 

Feature location

 

If your part has features that are located on different planes so that you need to constantly focus while moving from one plane to another, an autofocus feature will save a lot of time and effort.

 

Software Features

 

Ask for a demo of the system for your samples and check to see if the metrology software can perform all the required functions within the desired time frame. Also, compare the sample test report you got from the demo with the standard report and check the accuracy.

5 Major Functions of Optical Measuring Systems in Manufacturing

Image
In modern manufacturing, precision and speed are key to success. Optical measuring systems are essential tools that help ensure these qualities. These systems use light, such as lasers or cameras, to measure dimensions and detect defects in materials, offering a non-contact, highly accurate method for quality control.  In this blog , we’ll explore the five major functions of optical measuring systems and how they enhance manufacturing processes. Important Functions of Optical Measuring Systems  1. Precise Dimensional Measurement One of the core functions of an optical measuring system is the ability to provide precise dimensional measurements. This capability is crucial in industries such as electronics, aerospace, and automotive, where even the smallest deviation from specifications can result in defective products. For instance, optical systems can measure the thickness of PCB layers with micron-level precision, ensuring every component fits perfectly in the final assembly....

Top 5 Advantages of Coordinate Measuring Systems - Viewmm

Image
  Precision and repeatability in measurement are vital in today’s manufacturing environment. A Coordinate Measuring System (CMS), often built around a Coordinate Measuring Machine (CMM), plays a central role in maintaining tight tolerances and validating complex geometries. From aerospace to semiconductor manufacturing, these systems ensure quality, reduce rework, and support industry compliance. Below are the top five advantages of CMS, explained with core technical insights and real-world relevance. 1. High Accuracy and Repeatability Coordinate Measuring Systems operate using fixed axes and calibrated probes (touch or non-contact), offering micron-level precision. This is essential when inspecting parts like turbine blades or IC substrates where tolerances are exceptionally tight. Their repeatable measurements eliminate guesswork and variability common with manual inspection tools. 2. Versatility Across Part Geometries Whether it’s a small implantable medical device or a large a...
