A method for manufacturing a roll mold by cutting a roll, includes generating a control waveform based on a signal corresponding to a rotary position of the roll, and making a plurality of cuts on a surface of the roll by, while the roll is rotated, reciprocating a cutting blade in a radial direction of the roll in accordance with the control waveform. Making the plurality of cuts includes at each of a plurality of predetermined locations, making a predetermined number of cuts of predetermined depth based on the control waveform. Generating the control waveform includes generating a control waveform dictating that, when multiple cuts are made at a predetermined location, each subsequent cut will have a smaller depth than a preceding cut.

A cutter insert tool holder effects bidirectional linear cuts on a work surface. The tool holder includes two elongated slots sized to accommodate first and second cutting insert holders. The tool holder includes an actuator arm that is placed in a first pivoting position by contacting the work surface while the tool holder is displaced along the work surface in a first direction, the pivoting actuator arm causes an actuator cam to contact and engage the second cutting insert holder so that it is withdrawn while the first cutting insert forms a cut in the work surface. When the tool holder is displaced along the work surface in a second direction opposite the first direction, the pivoting actuator arm causes the actuator cam to contact and engage the first cutting insert holder so that it is withdrawn while the second cutting insert forms a cut in the work surface.

Generating the control waveform includes generating a control waveform dictating that the predetermined locations, the predetermined depths, or both are randomly selected. Generating the control waveform includes generating a control waveform dictating that, when multiple cuts are made at a predetermined location, each subsequent cut will have a smaller depth than a preceding cut.

Technology for turning selected portions of a workpiece by a cutting tool is described. The described technology can provide methods and apparatuses for turning areas of a part so that corner strikes are avoided upon material entry, burr formation upon material exit is eliminated or significantly reduced, and/or the instantaneous cut depth continuously changes to avoid notch formation. The resulting superior machining conditions can enable more aggressive machining parameters to be used in the tool path, thereby resulting in reduced machining time and load.

A controller of a machine tool determines in accordance with a machining program whether a first tool post is used to machine an unfinished workpiece. When the unfinished workpiece needs machining before terminating a continuous machining and when the controller determines that the first tool post is used to machine the unfinished workpiece W2, the controller simultaneously advances a first system and a second system in accordance with the machining program while preventing machining a workpiece held by the first spindle. When the controller determines that the first tool post is not used to machine the unfinished workpiece, the controller stops the first system and advances the second system in accordance with the machining program.

A method includes scanning a thickness of a workpiece in at least one point using a thickness sensor, determining that the workpiece is out of alignment in a cutting machine using the thickness sensor, and realigning the workpiece relative to the cutting machine or adjusting a machining operation using a controller of the cutting machine in response to determining that the workpiece is out of alignment.
