Automated CNC Measuring System

June 8, 2012

The new Jenoptik Wavemove automated surface roughness and contour measuring system includes up to seven CNC axes for complete measurement and evaluation of complex shaft or prismatic parts on the production floor.

Detailed, exportable analyses of the measuring results provide statements about the quality of the production process, based on many parameters from the automotive industry. The automated system eliminates reproducibility concerns and allows the user to track part quality through the entire manufacturing process, states the manufacturer.

Workpieces are positioned in a tilt fixture mounted on a rotary table on a granite base. A motorized measuring column automatically positions pickups, and the system automatically verifies the proper orientation of each part prior to measurement routine.

Roughness and contour measurement is accomplished by using probing systems for each type of measurement. The drive bar positions the roughness pickup even in hard-to-reach measuring positions. According to the company, the contour probe is easy to change and can be operated parallel to the roughness pickup if necessary.

The system provides:

• Uniform user interface for roughness and contour evaluations.
• Calculation of all common profile, roughness, and waviness parameters (more than 90).
• Evaluation of geometric characteristics such as distances, angles, and radii.
• Traverse length of 120 mm or 200 mm for roughness and contour measurement.

Measurement routines are selectable for specific features.

The system can also evaluate the twist on ground shafts, according to MBN 31007-07. Twist structures at sealing surfaces occur during grinding and impair the sealing function between the shaft and the sealing ring. The most important properties of these surface structures are measured three-dimensionally and the parameters relevant to the tightness determined.
