Inspection program QMSOFT® / QM-THREAD

The inspection program QMSOFT®/QM-THREAD is designed as a support system for the computer aided inspection for screw threads and screw thread gauges. All thread nominal values can be generated through this program in accordance with the following standards:

  • ISO metric screw threads according to ISO 1502:1996 (DIN ISO 965:1998)
  • Unified threads and thread gauges according to ANSI/ASME B1.1-1982/ B1.2-1983
  • Gauges for unified threads (ANSI/ASME B1.1-1982) according to BS 919-1:2007
  • Gauges for Metric M Screw Threads according to ANSI/ASME B1.16M-1984
  • NPSM pipe threads according to ANSI/ASME B1.20.1-1983
  • Screw taps according to DIN 802:1982
  • Pipe threads and gauges according to ISO 228:2000 (also the older DIN 259:1979)
  • Steel conduit threads according to DIN 40431:1972
  • ISO metric trapezoidal screw threads according to DIN 103:1997
  • Parallel screw threads of Whitworth form according to BS 84:2007 / BS 919-2:2007
  • Metrical thread inserts according to DIN 8140:1999 (EG threads)
  • HELICOIL threads according to Boellhoff factory standard
  • Knuckle threads according to DIN 405:1997
  • Buttress threads according to DIN 513:1985 (factory standard for gauge values)
  • Threads for valves according to DIN 7756:1979 and ETRTO V.7
  • ACME Threads according to ASME / ANSI B 1.5 – 1988
  • Stub ACME Threads according to ASME / ANSI B 1.8 – 1988
  • Hot-dip galvanised threads according to DIN 965:1999

The primary function of the program is to calculate all of the required gauge sizes and tolerances according to the thread standards and type of gauge being applied (for example: Screw thread GO ring gauge. After selecting the QM-THREAD standard, the type of gauge, (for example: Screw thread GO ring gauge) and entering the thread designation, for example: M20x1, all of the required gauge nominal values and tolerances will be calculated automatically. The limitations and restrictions of the norms being applied will be indicated. The program supports the nominal value generation and the measurement process for all types of thread gauges being standardised and also for all types of plain gauges used to check the minor or major diameter of screw threads.

The measurement process can be done according to VDI/VDE/DGQ 2618 guidelines or any other you wish to apply. Before using the program, the user should be familiar with the guidelines being applied as well as the measurement procedure for the inspection of screw thread gauges. Results can be produced on the screen and/or the printer and/or in a file. The nominal values of the gauge will be processed in connection with the inspection conditions and the measurement results in the results record. Tolerance excesses are marked and identified. It is possible to customize calibration certificates using the so called "certificate layout files" (templates).

The program can be started up directly from the QMSOFT®/QM-MANAGE gauge data management system. In this case it will receive all necessary nominal data necessary directly from the data base. At the end of the inspection the results and the calibration certificate will automatically be transferred back to the data base program.
