# What is 'Motion Design'?

Motion Design

There are many disciplines that use the term 'Motion Design': Graphic Design, and Dance Choreography, as examples.

However, in MechDesigner, we usually design the motions for machine elements during a machine cycle. In machinery, all the machine parts have mass and inertia. As such, forces between machine elements are also important. Parts with inertia must be moved carefully, especially as speeds are increased. If motions aren't designed carefully, machine elements will vibrate needlessly.

MotionDesigner

MotionDesigner, provides all the tools for you to design motions for high-speed packaging machinery.

Understanding Motion Design:

 1 A motion is a sequence of positions for a machine element - or a Rocker or Slider in MechDesigner.
 2 A motion-design satisfies a number of positional, velocity, acceleration and/or jerk specifications for the angle or distance between two parts throughout a machine cycle.
 3 When the number of motion requirements become extensive or complex, it is difficult to find one mathematical function that can satisfy the motion specification throughout a machine cycle.
 4 Therefore, it is convenient to split a motion into segments. The segments are joined end-to-end (concatenated, to be technical).
 5 The process of splitting into segments is called segmentation [The image shows a motion split into 4 segments].
 6 Each segment is given a different mathematical function, which we call a motion-law. Each motion-law is best suited to satisfy the motion specification during its segment period, without regard to the motion requirements of the other segments.
 7 The number of segments is a decision you must make yourself. Very complex motion requirements may need the segment to be split many times.
 8 The motion-law you choose for each segment is a decision you make yourself.  Each motion-law should have the capacity to deliver the motion specification during the segment period.
 9 A 'Blend-Point' is an instance where one segment ends and another starts.
 10 We have two editors in MotionDesigner to edit the motion:
 • Segment Editor
 • Blend-Point-Editor
