MarForm. Form Measuring Instruments Software Packages for Special Applications Expansion package for twist testing and evaluation Can be used in conjunction with MarForm MMQ 400 with T7W probe and Mahr's MarWin evaluation software consisting of Twist evaluation software package based on MarWin evaluation software Probe arm for T7W for twist measurement double-ended with diamond tip and carbide ball with 3 mm dia. for alignment Form and twist evaluation Form positional evaluation for ovality conicity parallelism parallel to twist evaluation Form positional twist evaluation of several upr values Evaluation and recording After the measurements have been performed measurement records with the following content are generated Twist parameters Movement rate DG (upr) 1 to 50 Period length DP (mm) 0.05 Twist angle Dy (degrees) maximum of 5 minimum depending on dia. 50 mm and DG (e.g. 15' if dia. 50 mm DG 15 upr) Twist direction negative positive or right left Twist depth Dt ( m) 0.1 Graphic output The measured profiles are output in the record as a graphic. Various types of graphic output are available 3D cylinder (in color traditional and unwound) Polar display of polar profiles for individual assessment of the workpiece form Amplitude spectra of the polar profiles in a bar graph Display of individual generating lines as a straightness profile for individual assessment of form and position parameters Amplitude spectra of the linear profiles in a bar graph Record with indication of measurement conditions Recording measured values Various contacting strategies can be easily parameterized Measurement of n generating lines (e.g. 72 according to DC standard) Combination measurement of n generating lines and m polar profiles (e.g. 4 4; high precision and low measurement time) Patented adaptive method (optimization of strategy and measurement time in computer) A probe arm for T7W equipped with two styluses is used to record measured values Stylus 1 with 3 mm dia. carbide ball for mechanical workpiece centering and tilting on the MMQ 400 Formtester Stylus 2 with diamond tip for measuring twist and form parameters Expansion package for piston testing and evaluation Can be used in conjunction with MarForm MMQ 400 with T7W probe and Mahr's MarWin evaluation software consisting of Software package for piston-specific evaluation based on MarWin evaluation software Probe arms for piston measurement optional and customized on request Within the framework of the piston testing and evaluation option piston-specific features and evaluations are implemented for example Determining the position of the main ovality axis Determining the position of the pin bore (using segment measurements in the bore) and using this to determine the ovality distortion Testing up to 10 ovalities using tolerance tables (symmetrical and asymmetrical) radius- or diameter-based input and output records for each oval polar and linear graphs and results table; changes possible at the customer's request depending on the work involved Testing 2 meridians using tolerance tables (symmetrical and asymmetrical) radius- or diameter-based input and output records both meridians on a single page with graphic and results table; changes possible at the customer's request depending on the work involved Determining the offset of the head relative to the defined piston axis Testing the following features in the grooves (for each groove measurements possible at up to 4 angle positions) - Long-wave (0 to 50 upr) and short-wave (15 to 150 upr) properties of upper and lower groove flanks - Groove opening angle (total and individual) of trapezoidal grooves output in either degrees minutes seconds or as a decimal - Straightness axial run-out and perpendicularity of upper and lower groove flanks relative to the piston axis Determining special linear forms of the piston's pin bore using tolerance tables (e.g. "trumpet shape") in the same clamping operation as items 1-6 (2 measurements for each bore section) Determining special linear (e.g. "trumpet shape") and polar (e.g. "ovalities on one side") forms of the piston's pin bore using tolerance tables clamped with centered bore (up to 4 linear and up to 2 polar measurements for each bore section) Twist measurement record H Request a brochure or see WebCode 1292.
