With the above given parameters a simulation run has been carried out when the cam profile is selected so as to generate a follower displacement x in the form. Base circle radius 50mm.

How To Draw The Cam Profile Ii Offset Follower Ii Moves With Shm Youtube

Return stroke with SHM for 90 0 cam rotation.

. Figure 6-13 Profile design of translating cam follower. Vectors xc and yc containing the coordinates of the cam profile are returned. With this assumption when s H q b.

Terms Used in Radial Cams Fig. Also assume when s 0 q 0 rise is to start when t0. Base circle radius 50mm.

It is a reference point on the follower and is used to generate the pitch curve. After you have mastered drawing parts with Mastercams 2D functions you are ready to move onto 3D part drawing. Vectors should all correspond to a full cycle of cam rotation from 0 to 2PI.

This moment tends to jam the follower in its guides. Remember to u s e a blunt H B penc il fo r t hes e s teps. Drawing Male Fac es f rom t he 34 View NEW.

In this tutorial you learn many 3D drawing techniques as you construct the connector and tool holder parts shown in the following pictures. Drawing handling compatibility of angular lines in Autocad. Dwell for 45 0 cam rotation.

Drawing in 3D opens a whole new world of possibili-ties. Select a point in the drawing to specify the center of the cam and to insert the cam mechanism. 2 x X abs sin ω t ϕ.

Now divide the base circle and the outermost circle by 300 sectors. I us ed a 4 B s o yo u c a n clearly see what Im d o ing. Again if a warning appears you may need to flip the mate direction.

1 Draw the cam graph as shown. Find In the Cam Design and Calculation dialog box define the cam mechanism in the following sequence. This time you have to select one of the Roller which are next to the first Roller you chose as the CAM Follower.

At each of these points abc draw circles of 5mm radius representing rollers. 1 Draw the cam profile for following conditions. The smallest circle drawn tangential to the cam profile with its center on the axis of the camshaft.

At the beginning of motion the knife edge of the follower contacts the point of intersection A of the base circle and the cam profile. Draw a base circle with center O and radius equal to the minimum radius of the cam ie. 74 Overturning Moment in Traslational Flat-Faced Followers.

Dwell for the remaining period. Construct base circle and prime circle 25mm radius. In reality the cam profile can be better visualized by imagining the cam to remain stationary while the contact points between cam and follower revolves round the cam in the opposite sense of the actual cam rotation.

Cam Follower Profile and then Location. Remember t he darker yo u go a nd t he ha r der yo u press the more difficult it will be t o eras e yo ur under-lay er s gui. Where X is the follower maximum displacement ω is the cam angular velocity and ϕ.

Dwell for the remaining period. The path of the tracer point. Out stroke with SHM for 600 cam rotation.

Return stroke with SHM for 900 cam rotation. When these boundary conditions are applied to the linear equation. Next insert the Output Disk into the assembly.

Dwell for 450 cam rotation. Let H Total follower rise Stroke b angular rotation of the cam corresponding to the total rise of the follower. The radius of the outermost circle is equal to the base circle radius plus the lift of the cam.

Now add another CAM Mate. Hence the cam will be aligned with AB. So there will be total of 12 sectors.

Obviously the smaller the stepsize the more accurate and smoother the final plot of cam profile. Profile of the cam when the line of stroke of the valve rod passes through the axis of the cam shaft The profile of the cam as shown in Fig is drawn as discussed in the following steps. The contour of the working surface of the cam.

Assume the cam turns clockwise. The cam profile points are generated so the follower axis is. The point at the knife edge of a follower or the center of a roller or the center of a spherical face.

Since there is no offset of the follower. In Figure 6-13 only part of the cam profile AK is displayed. The cam profile is the shape of the contoured cam surface by means of which motion is communicated to the follower.

The size of the base circle determines. Draw a prime circle with center O and radius. Follower type Knife edged in-line.

Rebuild the assembly to check that the mate was made properly. A 0 0 and a 1 H wb. 1 Draw the cam profile for following conditions.

Out stroke with SHM for 60 0 cam rotation. S a 1 qw a 0. In this case we want to keep the radius of the cam as shorter as possible to minimize this effect.

The following terms are important in order to draw the cam profile. 2 Draw a 20 mm radius circle and divide it into 30 divisions as shown. Velocity and acceleration during out.
