It is always important to try to improve the design of your motion when you need to improve the performance of a machine.
To design a motion:
1.Plan and sketch the Motion for the tooling, on paper, over one machine-cycle
Note on the sketch:
•The Motion's name - usually relate the motion's name to the function of the tooling or the interaction with the packaging. Try to make the name short.
•Each segment, with its approximate timing on the X-axis.
•The key positions of the tooling on the Y-axis. Example names for the positions may be: Out, In, Contact, ...
•If a segment has a velocity requirement - e.g. to track a pack during heat-sealing
•If a segment has a minimum time-periods - e.g. for heat-sealing jaws
•If the motion-cycle is progressive (indexing) or non-progressive (rise and return)
2.Use the Blend-Point Editor, to set the Y-axis position value of each Blend-Point to zero, then close the Blend-Point Editor.
3.If you need more than four segments, use Insert-Blend-Point command to split the motion into the number of segments you believe you need- or delete a segment if you need fewer segments.
4.Use the Blend-Point Editor to make sure the Match Control-Buttons are active for Position, Velocity, Acceleration for each Blend-Point - to make sure there is motion-continuity.
5.If the motion is a progressive motion, set the Blend-Point #1 to Do NOT Match.
6.If a segment has a particular motion-law , e.g. Constant-Velocity, use the Motion-Law Selector to change the motion-law.
7.Use the Blend-Point Editor to define the approximate X-axis value of each Blend-Point and the Segment-Width for each segment. Begin to define the duration of each segment making some shorter and others longer. The total duration remains as 360°.
8.Edit the Y-axis motion-values of each segment with the Blend-Point Editor and/or Segment Editor - to fully satisfy the motion requirements.
9.Make sure that none of the segments give a large spike in Acceleration compared to the other segments
10.If possible, avoid Jerk-discontinuities.
11.If possible, remove short Dwell segments. Try to replace with Zero Velocity, Acceleration, and Jerk at the Blend-Point.
