What is a Point-Cloud?
See also : Point-Cloud FB dialog-box
The term Point-Cloud is generally used to describe an array of coordinates that specify the shape of a 2D or 3D object.
Frequently, the shape is a cam that you want to reverse-engineer.
Point-Cloud FB
Use the Point-Cloud FB to:
•import coordinate-data that represents the 2D shape or cam
•fit a curve to the coordinate-data
The curve is mathematically smoother than the coordinates of the original data.
1.Measure an old Cam; import the Point-Cloud and define it as a new curve with the Point-Cloud dialog-box. 2.Use the curve, in combination with a Magnetic-Joint and a Graph FB to find the motion of a Cam-Follower. 3.Use the tools in MotionDesigner to identify the motion of the Cam-Follower. 4.We would usually redefine the motion with an improved motion. We use the improved motion to re-calculate the 2D-Cam. 5.Finally, you can recalculate the cam-coordinates and export them for cam manufacture. See also |
