Add Continuous Crank FB

Why should I use a Continuous-Crank FB?

In a Cam mechanism, you usually design the motion for a Tool-Part and MechDesigner calculates the motion of the Follower-Part with with Inverse-Kinematics. Typically the Follower-Part oscillates through an angle that is less than 180º, and usually less than 90º.

It also possible with Servo mechanisms to design the motion of a Tool-Part, but you want the motion of the Part that you drive with a rotating servo-motor to rotate by 180º, and even continually rotate.

A typical application of the Continuous-Crank FB is to find the correct length and rotational motion of a Crank to give the motion you design and want for a Tool-Part.

Add Continuous Crank FB

STEP 1: Add a Continuous-Crank FB to the graphics-area


1.Click Function-Blocks menu > Continuous-Crank


1.Click Modeling FB toolbar > Continuous-Crank FB


2.Click the graphics-area

The Continuous-Crank FB is now in the graphics-area and Assembly-Tree.

STEP 2: Open the Continuous-Crank dialog:

1.Double-click a Continuous-Crank FB in the graphics-area


See How to Open a dialog.

The Continuous-Crank dialog is now open.
