Manufacturing of worm gear in CNC lathe machine

Worm gear has been used to transmit motion and power inskewed axis. This is a gear that resembles a screw, with parallel helical teeth, and mates with a normal spur gear. The worm is in most cases the driving gear, there are however a few exceptions where the spur gear drives the worm. The worm gear can achieve a higher gear ratio than spur gears of a comparable size. Designed properly, a built in safety feature can be obtained: This gear style will self-lock if power is lost to the drive (worm). It doesn't work if the pinion is powered.Worm gears usually have been produced by conventional milling machine, however, these process have been increased manufacturing costs and timing.In this study, we have investigated machinability for worm gear in CNC lathe machine by using analysis process and a program being changed. This study, ıt was aimed to derive CAM codes automatically using MATLAB programme language for manufacturing of worm gear in CNC lathe machines. Because of this, a MATLAB programme was prepared according to main magnitudes of worm gear. Worm gear was obtained CAD model by using MATLAB programming. The CAM codes obtained by this CAD form. To control the accuracy of CAM codes, worm gear was simulated in CNC Simulator programme. After this, the programme was loaded to Fanuc lathe machine and the worm gear was produced and study was completed.
