About Motion Control
This section describes the positioning systems found in KVAL machinery. There are three basic
types of motion control methods used in KVAL Machinery.
Sequencing
Sequencing is a series of events executed in a predetermined order. Most KVAL machines use a
form of sequential motion control. A typical series of events for a KVAL machine are:
1.
Move the door into position.
2.
Clamp the door.
3.
Make the cuts.
4.
Unclamp the door.
5.
Move the door out .
6.
Wait for the next door.
Point to Point
Point to point motion control involves moving a load from one fixed position to another fixed
position at a constant speed and along one line (axis X,Y, or Z). A typical point to point would be
a drill with a fixed-depth. The drill is either retracted or extended using a pneumatic cylinder.
Typically the drills travel is limited by physical stops.
Incremental
Incremental motion control is used when the load is required to be moved with high accuracy to
multiple locations, sometimes in multiple directions (axes). A typical KVAL usage for this sys-
tem is a computer controlled router in a door light machine where there is great variety in the cut
size, shape and location.
