Frequently Asked Questions Do I need 2D or 3D measurement? If you only need to measure lengths, diameters, radii, angles and hole positions, a 2D or A-configuration system is usually sufficient. If you need to measure heights, depths, step heights or complex geometries, consider a B or D configuration. What is a touch probe? A touch probe is a precision sensor that physically contacts the part to measure features that cannot be accurately measured using optics alone, such as depths, heights and complex 3D geometries. What is a confocal laser sensor? A confocal laser sensor measures height and surface profiles without touching the part. It is ideal for delicate, polished, coated or highly reflective surfaces where contact measurement may be unsuitable. What is the difference between V3 and A6 Series machines? The V3 Series is designed for small to medium-sized components and automated production inspection. The A6 Series uses a bridge-style CNC structure and is designed for larger parts, moulds, tooling and fabricated assemblies. How do I choose the correct measuring capacity? Select a machine with an X and Y measuring range larger than your largest component. It is generally recommended to allow additional capacity for fixture positioning and future inspection requirements. Which configuration provides the most measurement capability? D Configuration systems combine optical vision measurement, touch probe measurement and confocal laser measurement in a single platform, providing the broadest range of measurement capabilities. Can Vision Measuring Machines generate inspection reports? Yes. Vision Measuring Machines can automatically generate measurement reports, first article inspection reports, SPC data and custom quality documentation depending on the software package used.
