4.8 Optimizing a Cam

Parameters

You can specify the parameters of the interpolation curve for the transition here.

You can set the following parameters:

Table 4-2		Parameters in the Parameters tab (Interpolation Curve Properties window)
		Field/button	Explanation/instructions
Jerk at boundary point
(allow interpolation by target device
deactivated)
(for 6th degree polynomial)
	Automatically		If you activate Automatically, the jerk value at the boundary points is
			calculated by the system. A polynomial of the 5th degree is used for the
			calculation.
			Note:
			You can activate this function via the context menu in the diagram
			representation: Right-click the transition and select Automatic jerk
			characteristic in the context menu.
	Left		If you activate Left, you can specify the jerk at the left boundary point of
	(automatically deactivated)		the interpolation curve. Enter the jerk value in the input field.
	Right		If you activate Right, you can specify the jerk at the right boundary point
	(automatically deactivated)		of the interpolation curve. Enter the jerk value in the input field.
	(Jerk value)		If you activate the option Left or the option Right, you can enter the jerk
	(automatically deactivated)		value here.
			Note:
			To specify an absolute jerk value, you must select an absolute master
			velocity for calculations in the Simulation Settings window.
Curve point of inflexion
(allow interpolation by target device
deactivated)
(for inclined sine curve)
(for modified sine curve)
(for modified acceleration trapezoid)
(for harmonic combination)
	Valid values are between 0 and 1		You can enter the turning point of the curve here.
	Optimum value		If you click this button, the optimum value for the turning point of the
			curve is calculated by the system and entered under Valid values are
			between 0 and 1.
			Note:
			You can activate this function via the context menu in the diagram
			representation: Right-click the transition and select Optimum value in the
			context menu.
