Form Measuring Systems handle workpieces up to 40 kg.

Press Release Summary:

Designed for workpieces up to 430 mm in diameter, Hommel-Etamic F435 and F455 complete fully automatic measurement of geometrical tolerances, surface roughness, and straightness in single setup. Advanced probe design permits roughness and waviness inspections along with form and position tolerance measurements via adjustment on rotary control. With CNC rotation and tilt module, fully automatic axial and radial measurements are performed without interruption.

Original Press Release:

New Automatic Form Measuring System

Jenoptik Industrial Metrology will demonstrate the new Hommel-Etamic F435 and F455 automatic form measuring system at IMTS 2012 Booth E-5545. The system 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, thus significantly enhancing productivity.

Designed for workpieces of up to 40kg weight and 430mm in diameter, the systems can measure products such as gear shafts, injection parts, bearing rings, valves, connecting rods and pistons. Jenoptik offers specialized solutions to extend the application scope to include brake disc measurement as well. Individual configuration allows optimum measurement situations for specific tasks.

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

Automatic centering and leveling of the work piece helps deliver the highest possible 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 all combine to deliver superior 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.

Parameter-oriented operation

The improved productivity is enhanced by the TURBO FORM evaluation software. The graphical, function-oriented user interface guarantees simple operation even for complex measuring tasks. Besides evaluation and presentation of all form and position parameters, the software also includes evaluation features 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®.

Twist measurement according to Daimler standard

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 Daimler standard MBN 31007-07 from 2009, 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 5mm to 2mm constitutes a singnificant time savings.
