4.7.3.2 Interpolation (2)
Cam disk type
I the "Interpolation(2)" tab of the CamEdit dialog box, you can set the marginal
conditions for interpolation at a certain cam disk type.
Programmable conditions:
Cam type Condition Cam profile
Non-cyclic None The cam disk is tracked once only.
The edge points and gradients can be define
freely and are not influenced.
Cyclic, relative Constant velocity The first derivative of the function is equaled at
the edge points.
That is, the velocity at the start point of the cam
is set equal to that at the end point.
Cyclic, absolute Constant velocity and
function (constant
position)
At the edge points, the first derivative of the
function is equaled to the function value.
That is, the velocity at the start point of the cam
is set equal to that at the end point. This also
applies to the start and end positions of the
cam.
If the continuity condition can not be adhered to because of the selected
interpolation method or the programmed geometry, a message is provided to that
effect.
Master range
You define the edge points of the interpolation by setting the master range.
A programmed geometry which lies in between the start and end position of the
master range is discarded. If the start or end points are outside the range of the
programmed geometry, this gap is extrapolated based on the interpolation method.
