Two-tone test and measurement. The two-tone test to measure IMD has been a vital part of analog radio for years, and is still important in digital radio for preliminary testing. To measure the two-tone third-order products at the output of a receiver at a set RF input level hook up the test gear and receiver as shown in Fig. 2.46. Feed two signals, equal in amplitude and closely spaced in frequency, from the two signal generators into the combiner. The combiner, which will

cams has in some instances reduced wear. However, it has been observed that cam surface nishes better than 15 m in rms can induce errors in the cam pro le that will affect cam dynamic loading (acceleration curve shape) and as a result nullify the result of the improved surface nish. The limit on nishing can be determined by experience and by cost. Finishing of cams is the most critical of the fabrication operations. The basic point for consideration is how smooth the surface must be for the ultimate fatigue life and follower performance. This subject was discussed in Chap. 9. A milled cam surface nish can be held to 125 m in rms. Grinding is the most accurate cam- nishing operation and surface nishes as ne as 15 m in rms can be obtained. Figure 10.5 shows a DRD ground cam acceleration curve with high-frequency oscillations at points of maximum acceleration. Barkan (1953) showed that analog ground cams tend to have high-frequency inaccuracies. However, these high-frequency inaccuracies have very little effect on the dynamic action of the cam-follower system at moderate speeds. Roller followers have been nished as smooth as 4 m in rms. Polishing of automotive sliding followers as high as 50 m in rms is acceptable. Lapping is sometimes utilized to correct minute heat treatment distortion errors in multiple hardened cams. An abrasive lapping compound is used to t mating cams and followers. Sometimes if a surface needs improvement a shear polish, lapping operation, or controlled run-in period is employed, all limited by cost. Machine frames should be chosen to be as rigid as possible so as not to detract in any way from the proper, accurate function of the cam-follower mechanism. If the frame is soft, it may store and release energy in every cycle of operation. Next, let us discuss the cam curve mathematical analysis as it relates to the accuracy of manufacturing the actual cam. It should be noted that there is a limit in design to control the higher order derivatives of the cam curve. In cam analysis, it is conventional to use the smooth acceleration curve as a basis for analysis. The curve choice is selected accordy ingly. This is compatible with the usual manufacturing tolerance of 0.001 in. It has been shown by Kim and Newcombe (1983), Barkan (1953), and Weiderrich (1973) that extreme manufacturing limits of 0.0001 in tolerances cannot control the jerk. In general, for industrial production machinery the jerk curve is used basically as a guide and not as a design tool. Hence, given normal manufacturer tolerance, it is not possible to control higher order deviation. Thus, it is not signi cant to elaborate on the jerk curve since it cannot be controlled in manufacturing easily. Last, let us discuss the total machine tolerance analysis to reduce the accumulated error in the system. This method consists of a weighting factor for each of the connected parts of the machine. In this manner the engineer can determine and control the tolerance of each member that contributes most to the error. The manufacturing tolerances can then be modi ed to improve the machine performance. Sometimes a change in manufacturing methods is helpful.
