# What is 'Motion Design'?

#### Motion Design

There are many disciplines that use the term Motion Design: E.g.: Graphic Design, Dance Choreography.

However, in MotionDesigner, we usually design motions for machine elements for a machine cycle. In machinery, all the machine parts have mass and inertia. As such, the forces that develop between machine elements that are a result of their motions are also important. Parts with inertia must be moved carefully, especially as speeds are increased. If motions are not designed carefully, machine elements will vibrate needlessly.

#### MotionDesigner

MotionDesigner, provides all the tools to design motions for high-speed, multi-axis machines, such as those found in the packaging, assembly, textile industries.

 What is 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 position, velocity, acceleration, and/or jerk specifications for the angle or distance between two parts throughout a machine cycle. 3.When the number of motion specification 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. Segments are joined end-to-end (concatenated, to give the technical term). The number of segments in the machine-cycle is dependent on the number of different motion requirements in the machine-cycle. 5.The process of splitting into segments is called segmentation. The image above shows a motion split into 4 segments. 6.Each segment may have a different math function, which we call its motion-law. We select the motion-law that can satisfy the motion specification during its segment period. 7.A Motion-Law will have different parameters that you can use to satisfy the motion specification. 8.A Blend-Point is at the instant when one segment ends and another starts. 9.We have two editors in MotionDesigner to edit the Blend-Points, and Motion-Law. and any other parameters.
