Results of An Arc Programmed with Radius Command, Example 12.5

Important: Any axis that is not specified when programming a circle

remains at its current axis position value. This results in the end point of

an arc having the same coordinate value as the start point of the arc for that

If you do not speci fy the end point of the arc, or if the end point is the same

as the start point, two different results are possible:

if you use I and/or K to program the arc center, a full circle i s made

if you use R to program the radius of the arc, no arc is made (the control

does not move either axis)

Example 12.6

Arc End Points Same as Start Points

Arc1-Full Circle Arc 2-No Motion
