Video 'How to design a Progressive (indexing), 6-segment motion
Before you edit MotionDesigner, do a basic motion plan, on paper, for each machine-axis (tool)
Basic Motion-Plan on Paper.
Sketch the X-axis:
•Add a machine-cycle of 360°
•Split the X-axis in half, and in half again, to add the 90°, 180°, and 270°.
•Add a check mark every 30°
Estimate for each tool for one machine-cycle of 360°:
•The number and approximate number of degrees for each segment
•The distance or angle the tool moves in each segment
•Note if a segment has a 'special' motion requirement - e.g. constant-velocity
Sketch the Timing Diagram for one machine-cycle of 360°:
•Draw a straight-line between each Blend-Point (from each intersection of X and Y-axis values)
Transfer the Basic Motion-Plan from paper to Motion-Designer.
Watch the video below to see the best way, I believe, to transfer the Motion-Plan from paper to MotionDesigner.
In the video you will see how to design a 6 segment, progressive (indexing) motion.
Summary of Video:
1.Start from the default motion. It has 4 segment, all Flexible-Polynomials.
2.Set all Positions to zero - use the Blend-Point Editor
3.Add two new Segments - use the 'Blend-Point and Segment Editor: Insert Blend-Point At...' tool two times.
Each time you use this tool, one segment becomes two segments. The Motion-Width will not increase.
4.Edit the X-axis of each Blend-Point - see Blend-Point Editor.
I usually start by moving X-axis for the Blend-Point that does not need to move much along the X-axis. I do that so that X-axis of a Blend-Point does not 'bump' into a Blend-Point to its left or right.
5.Edit the Position of each Blend-Point - see Blend-Point Editor
6.Edit the Motion-Laws of each Segment - see Motion-Law Selector
