تصميم الشكل الهندسي للمسامير الملولبة(النظام المتري)

Abstract

The aim of this research is to computerized design of thread forms (ISO Metric thread) by converted geometrical description of thread forms elements into mathematical equation which have well coherency with one of most popular (CAD) format file that is Data Interchange Formats File (DXF). The developed (CAD) part of the system of thread forms designs allows automatic thread forms drawing generation using the AutoCAD Rel.2000 package thus by using (DXF). The developed system was tested and showed beneficial results when applied to thread forms design and found the capability to obtain thread forms in three dimensions with reduced time and efforts and high accuracy.
