摘要： The invention relates to a method for suppressing regenerative chatter of the kind which occurs during the machining of workpieces by a tool of a machine tool, said method consisting of changing repeatedly the cutting speed of the tool whilst the latter machines the same surface of the workpiece, thereby making the frequency with which the waves or ripples on the surface which is being machined impact on the tool dissimilar to the inherent frequency of the mass system on which the cutting force acts, so that these waves or ripples when impacting on the tool do not increase the amplitude of the vibrations which product chattering. Moreover the invention relates to a machine tool for carrying out such method, more particularly to a lathe.

摘要： The subject matter of the present invention is an installation for machining crankshafts, camshafts or like workpieces. Each of the workpiece is mounted in non-rotary condition in a workpiece holder. A plurality of such workpiece holders is guided on a straight path with their workpieces in co-axial relationship to each other and to said path. A plurality of tool units is distributed in spaced relationship along the path. Each unit includes an annular rotary tool having internal cutting edges. This tool surrounds an internal clearance space which is larger than the cross-section of the workpiece holders. Therefore, each tool affords passage of said workpiece holders through the clearance space. Each of the tool units further comprises means for moving the annular rotary tool into a position in which its internal clearance space is in registry with the path of the workholders. Conveyor means are provided for intermittently transporting said workpiece holders with the workpieces on a guideway along the path through the clearance spaces of the tool units and for temporarily stopping each workpiece holder in a position in which its workpiece is surrounded by said annular rotary tool and in a position to be machined by the cutting edges thereof. The conveyor means may comprise drag members which are distributed along the path and are adapted to engage the workpiece holders. These drag members are reciprocated parallel to said path in synchronism with each other and thereby feed each of the workpiece holders step by step along the path consecutively through the annular rotary tools.
