QMSys Thread-PD

QMSys THREAD-PD helps the user to determine the indicated values when the pitch diameter is specified as well as to determine the pitch diameter of threads when the indicated values are specified. It is suitable practically for all types of threads:
ï¿­ external and internal
ï¿­ symmetrical and asymmetrical
ï¿­ single-start and multiple
Indicated values and pitch diameters are determined using measuring wires or balls by Berndts iteration formula from the publication EA - 10/10. The correction for the measuring force is defined by Lechowskis methods. The optimum diameter of wires or balls is calculated by the formula published in EA - 10/10.
The parameters to be entered and calculated are given in the left-hand side of the software.
The following are given in the right-hand part of the appendix:
ï¿­ measurement diagram for the selected type of thread
ï¿­ catalog of diameters; they are edited by using the buttons "New" and "Delete". The "Select" button selects the diameter of wires/balls.
