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 tool over one machine-cycle
Note on the sketch:
•the Motion name - usually relate the name to the tooling function or interaction with the packaging. Try to make it short.
•the key positions of the tooling
•each segment
•if a segment has a velocity requirements? - 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 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-Button for each Blend-Point is set to Do Match.
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.
There should not be any acceleration discontinuities.
If possible, avoid Jerk-discontinuities.
If possible, remove short Dwell segments. Try to replace with Zero Velocity, Acceleration, and Jerk at the Blend-Point.
8.Complete the motion design for all of the axes on a machine.
