Jenoptik Industrial Metrology  HommelEtamic

A CNC rotation and tilt module allows fully automatic axial and radial measurements without interruption. Individually motorized axes for tilting (90°) and rotating (270°) allow the probe to access difficult to reach measuring positions.

IMTS 2012: Jenoptik Fully Automatic Metrology System

Measures workpieces weighing up to 40 kg, 430 mm in diameter Available for desktop or a complete workstation Automatic centering, leveling maximizes precision

Jenoptik Industrial Metrology will demonstrate its new Hommel-Etamic F435 and F455 automatic form measuring systems, which the developer explained “completes fully automatic measurement of geometrical tolerances, surface roughness and straightness in a single setup.” An advanced probe design permits roughness and waviness inspections along with form and position tolerance measurements via a simple adjustment on the rotary control, making the CMM process “significantly” more productive, according to Jenoptik.

Both models are designed to measure workpieces weighing up to 40 kg and 430 mm in diameter. Examples of products that can be measured effectively include gear shafts, injection parts, bearing rings, valves, connecting rods, and pistons. Jenoptik offers options to extend the application scope to include brake disc measurement. Individual configuration allows optimal measurement situations for specific tasks, it said.  

Available as a compact desktop version or a complete ergonomic measurement workstation, the systems include a frictionless air-bearing rotary table that ensures the reproducibility of even small tolerances over long periods of time.

Automatic centering and leveling of a workpiece helps to maximize precision over the full measuring distance and compensates for possible inaccuracies caused by wobble. High-precision guides equipped on both the R and Z axes and specially designed drive systems combine to deliver precision and speed.

A CNC rotation and tilt module provides fully automatic axial and radial measurements without interruption. Individually motorized axes for tilting (90°) and rotating (270°) allow the probe to access difficult to reach measuring positions. The probe direction is reversible with variable free-stroke limits in both directions.

The improved productivity is enhanced by Turbo Form evaluation software. The graphical, function-oriented user interface guarantees simple operation even for complex measuring tasks. Along with evaluating and presenting all form and position parameters, the software also evaluates for all typical roughness and waviness parameters. For continuous monitoring of the production process, all measurement results can be transferred to a central statistics server via qs-STAT®.

Standard options of this class of measurement device include second-generation twist measurement for rotating seal surfaces on crank or gear shafts according to Daimler standard MBN 31007-07.

Twist measurement is used to evaluate the dynamic sealing properties of a surface using shaft seals. According to the current (2009) Daimler standard MBN 31007-07, all new parameters such as theoretical feed cross-section per revolution DFu, or the contact length in percent DLu, can be determined using optimized evaluation algorithms. Thanks to optimized evaluation the measurement results are much more stable, and the reduction of the evaluation length from 5 mm to 2 mm saves a significant amount of time.
