Design of fit with the computer aid

In this study, a computer program has been written for aid to the determination of interference fits and design such as gear, pulley and bush connected with shafts. Program has been written by Visual Basic 6.0 and AutoCAD aided VBA (Visual Basic for Application) languages. The thesis program consists of four parts. In the first part, standard tables of related to interference fits have been transmitted to the Access data form and tolerance values have been calculated according to diameter and tolerans grade by using Access datas. In the second part, controls of mechanical and stress have been made in condition of interference fit. Choice of tolerance and manufacturing methods have been performed for will be moved to the moment. Interference fit has been drawn by AutoCAD aided VBA. In the third section, related to interference fit tables have been presented. In the fourth section, the determination of manufacturing methods have been made according to the quality of IT.Key Word: Fits, tolerance, VBA
