Tool Vision Measuring Machine: A Precise and Efficient 2D Measurement Solution

In the field of precision manufacturing, achieving fast, high-accuracy, and non-contact dimensional inspection is critical for ensuring product quality and improving productivity. Traditional measuring tools such as calipers, micrometers, or monocular microscopes are prone to human error, offer limited repeatability, and require complicated operations—making them less suitable for modern quality control demands.

To address this, the Tool Vision Measuring Machine, a high-performance optical inspection device tailored for tool measurement, was developed based on manual vision measuring machines. It retains the strengths of manual models while enhancing structural stability and functionality, delivering high-precision measurement with ±3μm accuracy.

I. Structural Upgrades: Classic Inheritance with Comprehensive Optimization

The Tool Vision Measuring Machine inherits all the advantages of manual vision machines—non-contact measurement, high magnification, clear imaging, and flexible operation—while introducing key enhancements in the following areas:

1. Granite Base: Ensuring Structural Stability

The machine features a natural granite base with excellent density and stability. It has a low thermal expansion coefficient and resists deformation, making it ideal for long-term usage. Compared to traditional iron or metal bases, the granite platform offers:

Stable support to reduce micro-vibrations affecting accuracy

Long lifespan with no deformation over time

Resistance to humidity and temperature changes

Reliable performance in both laboratories and production floors

This structural design forms the physical foundation for achieving ±3μm measurement accuracy consistently.

2. Dual-CCD Imaging System: Comprehensive Viewing Angles

Tool geometries are often complex, including blade length, tip angle, rake angle, clearance angle, chamfer, and spiral angle. A single viewing angle is insufficient for complete analysis. Therefore, the system is equipped with two industrial-grade CCD cameras and lenses, enabling multi-angle observation:

Primary CCD: Captures top-down images to measure tool profiles, lengths, widths, and diameters.

Secondary CCD: Captures side views to analyze spiral angles, rake angles, and clearance angles.

This dual-CCD setup eliminates the need to move or reposition the workpiece, reducing human error and improving measurement efficiency and repeatability.

II. Optical & Software Collaboration: Greater Accuracy

1. High-Magnification Telecentric Lens System

Equipped with industrial telecentric lenses, the system avoids parallax and image distortion, ensuring precise edge detection and shape capture. Key features include:

Sharp edge rendering with clear contours

Size consistency regardless of workpiece placement

Enhanced detection of tool edges, holes, and chamfers

This is especially critical for measuring micro-tools and fine metal components with reliable accuracy.

2. High-Resolution Image Capture System

The CCD cameras offer a resolution of 1.3 megapixels or higher, ensuring high-definition imaging and fast data processing. The system can rapidly identify edges and dimensions while maintaining stable measurement within the ±3μm tolerance range.

3. Intelligent Image Processing & Measurement Software

Integrated with proprietary or third-party measurement software, the system supports:

Automatic edge detection

One-click measurements of angles, lengths, radii, etc.

Template-based inspection for batch measurement

Data reporting, SPC statistical analysis

Image annotation and CAD overlay comparison

This transition from manual reading to automated measurement greatly improves consistency and efficiency.
