Optical measurement of turned and ground shafts

Mechanical shafts are precision components manufactured through turning and grinding operations. Their axially symmetrical geometry, with cylindrical, tapered, or contoured surfaces, requires highly accurate dimensional inspection.

Measuring turned and ground shafts is essential to ensure proper fit, smooth rotation, and consistent mechanical performance in demanding industrial applications.

The main geometric characteristics of turned components

  • external diameters

  • shoulders and grooves

  • chamfers, radii and angles

  • threads

  • roundness and cylindricity

  • run-out and coaxiality

  • distances

The precision of these geometries is essential to ensure the correct operation of the component within the mechanical assembly.

The optical measurement system and dedicated software enable you to:

  • capture the complete profile of the component

  • perform measurements along the entire length of the shaft

  • evaluate deviations from nominal dimensions

  • obtain immediate results for in-process quality control

With VICIVISION, measurements are completed in just a few seconds using non-contact optical technology that captures the image of the rotating part between centers.
The intuitive software makes the system easy to use, even for operators without advanced metrology expertise.

Overcome the most common challenges in measuring turned parts

Measuring turned components can present several challenges when performed with traditional instruments:

Problem

Typical measurement challenges include: long measurement times, risk of human error, difficulty in measuring, complex profiles, need to use multiple inspection tools, possible deformation due to contact, poor repeatability between different operators.

Solution

Key benefits include: fast measurement in just a few seconds, complete inspection of the part profile, high measurement repeatability, reduction of human error, no contact with the component, ease of use on the shop floor.
