Designing of helical involute gears involve several parameters to be considered. It includes the calculation of the gear parameters, the use of several commercial packages such as Autodesk drafting package, solid work package, Ansys package … etc. The commercial packages are usually work on standard gears. Their libraries store gears that can be used by inserting the standard parameters not the modified parameters. When dealing with modified gears the profile is digitized and fed as discrete points to the package. As the modifications involve profile modification, gear undercutting, tip relief, inserting of gear backlash which result in varying all gear parameters, so a need to computerize this process and present a file that is read by the majority of the commercial packages. This paper gives a software interface capable of calculating all the parameters of involute helical gears including their modifications and saves them in Formatted files that can be read directly by the other gear packages.
