In Chap 2, the characteristics of displacement, velocity, acceleration, and jerk of basic symmetrical curves were presented These curves were employed because of their simplicity of mathematical analysis and ease of construction However, for many machine performance requirements, as when the cam requires either special functional motions or must operate at high speeds, the basic symmetrical curves are inadequate and modi cations in curve selection are necessary These modi cations can consist of blending, skewing, or combining sectors of the cubic curves, simple harmonic curves, cycloidal curves, constant velocity curves, and constant acceleration curves Last, it should be mentioned that cam curve development (not shown) can be accomplished by starting with the fourth derivative (dify/dyif) curve with numerical trial and error combined with past experience to nd the ultimate desired cam shape Computers are employed to perform the increment integration in determining the displacement velocity, acceleration, and jerk curves Curve development and selection is one of the primary steps in the design of any camfollower system Later chapters include investigation of the pressure angle, cam curvature, cam torques, lubrication, materials, and necessary fabrication tolerances, among other things A typical design evolutionary process will proceed as a series of trade-offs to produce the nal design This chapter has two parts: complete mathematical development for popular DRD curves a simpli ed procedure for combining sectors of various basic curves The dwell-rise-dwell (DRD) and dwell-rise-return-dwell (DRRD) curves will be analyzed The rise-return-rise (RRR) curve is not presented since the eccentric mechanism of Chap 15 satis es the action in a simple, reliable, less expensive way The RRR curve is also best for high-speed requirements because it provides a motion curve having continuity in all of its derivatives Note that the DRD cam curve is a portion of the total action which could be a part of the dwell-rise-dwell-return-dwell (DRDRD) cam Figure 31 shows the complete cycle of blended DRD cycloidal curve producing a DRDRD cam The period of rise is smaller than the period of fall, producing higher rise maximum acceleration than the maximum fall acceleration.

delegate void MyEventHandler(); // Declare a class that contains an event class MyEvent { public event MyEventHandler SomeEvent; // This is called to raise the event public void OnSomeEvent() { if(SomeEvent != null) SomeEvent(); } } class X { /* This is a static method that will be used as an event handler */ public static void Xhandler() { ConsoleWriteLine("Event received by class"); } } class EventDemo4 { static void Main() { MyEvent evt = new MyEvent(); evtSomeEvent += XXhandler; // Raise the event evtOnSomeEvent(); } }

In the program, notice that no object of type X is ever created However, since Xhandler( ) is a static method of X, it can be attached to SomeEvent and executed when OnSomeEvent( ) is called

Nesting filters can be rather tricky First and foremost, you must have a clear understanding of what you want nested and what filters you wanted connected with an AND or OR 1 To add a nesting or another AND / OR connector, select the block from within the Document Structure And Filters on the left, and then select Filter to call the Filter Editor If you have selected just an individual column, your dialog will be different from that shown in Figure 19-7 2 Click the Add Nested Filter button on the right of the Filter dialog This will insert an AND connector leftmost 3 Double-click the AND to toggle it to OR Use drag and drop to reposition the connectors and filters 4 Click Apply

The form of event used in the preceding examples created events that automatically manage the event handler invocation list, including the adding and subtracting of event handlers to and from the list Thus, you did not need to implement any of the list management functionality yourself Because they manage the details for you, these types of events are by far the most commonly used It is possible, however, to provide the event handler list operations yourself, perhaps to implement some type of specialized event storage mechanism To take control of the event handler list, you will use an expanded form of the event statement, which allows the use of event accessors The accessors give you control over how the event handler list is implemented This form is shown here:
