Urgency of the research. Providing high precision cam camshafts and textile machinery while ensuring high processing performance of these parts is an urgent task in the engineering, automotive and textile industries. Target setting. The high accuracy and quality of machined curved surfaces of the cams will ensure the correct operation of the nodes and will increase their service life. Actual scientific researches and issues analysis. Known methods of processing the curved surfaces of the cams
... faces of the cams of the camshafts, but in these methods, the flow along the contour is uneven, the depth of cut is different, which reduces the accuracy of the machined part and the processing performance. Uninvestigated parts of general matters defining. The study of the process of rough and fair milling of the curved surfaces of the cams of the camshafts and textile machines oriented mill for one installation, which will provide high rates of accuracy and productivity of processing. The research objective. The development of a new method of rough and fair milling of the curved surfaces of the cams of the camshafts and textile machines with crossed cutter axes and parts in one fastening will provide an increase in the accuracy and quality of the processed surfaces and processing performance. The statement of basic materials. The presented method of milling the curvilinear surfaces of the cams of the camshafts, where the roughing and finishing work is carried out by a cutter whose height is less than the length of the cam. Milling of all cams of a camshaft is carried out in one fixing with a tool with crossed axes and parts. When machining the cam-shaped cam surfaces, stabilization of the contour feed and removal of the seam allowance is ensured. That provides increased accuracy and processing performance. Conclusions. The proposed method of milling the curved surfaces of the cams of the camshafts and textile machines with crossed axes of the cutter and parts. The proposed method of milling curvilinear surfaces on CNC machines, where in one pass, roughing and finishing milling of all cams takes place.
