Cams are essential mechanical elements for transmitting mechanical motion and work to another components according to a prescribed function. Typically, cams are widely used in many automatic equipments, such as textile machinery, internal combustion engines, transfer presses, and other automatic devices. However, complex engineering tasks are required in a design and manufacturing of cams. And also, the manufacturing of general cam is demanded high costs.
Generally, cam manufacturing is followed by procedures, which are CNC milling machining, heat treatment, and final grinding machining.
A cam profile CNC grinding machine is developed for manufacture of high precision contoured cams. In this paper, structural and modal analysis for the developed machine is carried out to check the design criteria of the machine. The analysis is carried out by FEM simulation using the commercial software, CATIA V5. And also, this paper presents the measurement system and experimental investigation on the modal analysis of the grinding machine. The weak part of the machine is found by the experimental evaluation. The results provide structure modification data for good dynamic behaviors. And safety of the machine was confirmed by the modal analysis of modified machine design.
In order to obtain the positive motion of follower by rotating cam, its shape should be correctly designed and manufactured. In present paper, a CAD/CAM system is developed for shape design of disk cams using relative velocity method and NC-code generation using the biarc curve interpolation and the proposed algorithm, which is calculation of the maximum rotating speed to obtain constan surface roughness. And, the cam profile measuring system is developed in order to evaluate the manufactured cam. The developed system is composed of servo motor, CNC controller, rotary encoder, and laser-CCD interferometer. And also, this system is non-contact measuring type. Experimental measuring is carried out for the grinding manufactured cam. It is shown that the developed CNC grinding machine and the operating CAD/CAM system can be effectively applied to the manufacturing of precision cams.
