How to done this circular profile?
can any one explain that..i dont know about Q and P value..how to do this profile..???
What you need to do is start by drawing the 0 deg. circle indicated in the drawing. The Q value is the the angle the center of the circle is at. The P value is how far away the circle is from the center. Its easier to start the 0 deg circle straight verticle and then follow the given pattern accordingly. The lines that are left blanks are jumps in between angles. Once you draw all the circles in appropriate positions, draw a tangent line around the outside of the circles which would create the cam shape.
