Statistical Process Control (SPC) Using Video Measuring Systems (VMS) and Coordinate Measurement Machines (CMM) Measurement Data
Dimensional inspection systems such as Video Measuring Systems (VMS) and Coordinate Measurement Machines (CMM) are capable of producing highly accurate and repeatable measurement data. However, collecting precise data alone does not ensure process stability or product quality. In many cases, manufacturers rely on pass/fail inspection without fully utilizing the generated measurement data. As a result, […]
Tips for Selecting the Right Measurement Equipment for Industrial Production and Quality Control
Selecting measurement equipment for production is not just a purchasing exercise. It is a process control decision. Inaccurate or unstable measurement systems can lead to false rejects, undetected defects, and unreliable quality data. As production tolerances tighten and compliance requirements increase, the impact of incorrect equipment selection becomes more severe. This article is intended for […]
From Measurement to Decision: How Inspection Data Drives Quality Control
Modern manufacturing has made significant progress in the ability to measure parts with high precision. However, measurement alone does not improve quality. The real impact comes from how inspection data is interpreted, communicated, and used to guide decisions. When used effectively, inspection data becomes more than a record of results. It becomes a key driver […]
Precision Measurement Challenges in Microelectronics Manufacturing
Precision measurement is the backbone of microelectronics manufacturing. As components shrink to micro- and even nanoscale dimensions, even the smallest deviations can result in functional failures or reduced yield. In an industry driven by tight tolerances and high-volume production, maintaining accuracy, repeatability, and consistency is critical to ensuring product quality and process reliability across all […]
Maintaining Long-Term Stability and Accuracy in Coordinate Measuring Machines (CMM)
Coordinate Measuring Machines (CMM) are essential tools in quality control, enabling precise measurement of complex components across industries. While these machines are designed to deliver high accuracy, achieving reliable results over time requires more than the machine’s initial performance at installation. Long-term measurement accuracy is not defined by initial specifications alone, as performance can be […]
Probe Technology in Coordinate Measuring Machines (CMM): Touch Trigger Probe vs Scanning Probe
Within a Coordinate Measuring Machine (CMM), the probe plays a critical role as the interface between the machine and the measured workpiece. While the Coordinate Measuring Machine (CMM) itself provides precise motion control and positioning, the probe determines how measurement data is captured from the workpiece surface. As different measurement tasks require different methods of […]
Understanding Measurement Uncertainty in Video Measurement System (VMS) Inspection
When inspecting a precision component, the measured dimension is often treated as an exact value. In reality, every measurement carries a degree of uncertainty that must be considered when determining whether a part truly meets its tolerance requirements. Understanding measurement uncertainty is therefore essential for reliable dimensional inspection. This article explores the concept of measurement […]
The Science Behind Non-Contact Optical Measurement in Video Measurement Systems (VMS)
Non-contact optical measurement refers to the acquisition of dimensional and geometric data without physically touching the measured component. Instead of mechanical probes, these systems rely on controlled illumination, precision optics, and digital imaging to extract measurable information from reflected or transmitted light. As manufacturing tolerances continue to tighten and component geometries become increasingly intricate, traditional […]
