Designing a Screw for Servo Motor in CATIA V5: Step-by-Step Tutorial

Welcome to this tutorial on designing a screw for a servo motor using CATIA V5. If you're not familiar with servo motors, they are a type of motor that is commonly used in robotics and automation applications, due to their ability to provide precise control over the position, velocity, and acceleration of a rotating shaft.
In this tutorial, we will go through the step-by-step process of creating a screw design that is used in servo motor, using the powerful tools available in CATIA V5.
We will use CATIA V5 to create a new part and define the basic parameters for the screw design, such as its diameter, thread pitch, and length. We will then use the various sketching tools available in CATIA V5 to create the 2D profile of the screw, which we will extrude to create the 3D model.
Once we have the basic shape of the screw, we will use CATIA V5's advanced modeling features to add details such as threads, chamfers, and fillets, all of which are crucial to ensuring that the screw functions properly with the servo motor.
By the end of this tutorial, you will have a solid understanding of how to design a screw for a servo motor using CATIA V5,

In mine the head is not circular it became an octagon

To get the perfect Circle, you can try changing the settings:
Go to options → display → performance → in 3d accuracy and 2d accuracy, enable proportional and keep value as 0.01

@@designthoughts2570 Thanks man this was really bugging me, I drew a circle and thought it was a visual thing but this confirmed my theory.
Now it's a circle. :-D
