A method of machining a workpiece may include continuously rotating the workpiece, continuously rotating a tool having at least one cutting surface, and positioning the tool relative to the workpiece so that the at least one cutting surface engages the workpiece at a first discrete location at a periphery of the workpiece. The method may further include continuing to rotate the workpiece and the tool so that the at least one cutting surface engages a second discrete location at the periphery of the workpiece, and controlling a tool surface velocity VT relative to the workpiece surface velocity VW so that the first and second discrete locations are discontinuous. The tool may make multiple iterative passes over the workpiece to engage subsequent discrete locations, wherein the first discrete location, second discrete location, and multiple subsequent discrete locations may form a machined surface that extends continuously around the workpiece.

Compound machining method and apparatus

A system is provided for manufacturing a part. The system includes a manufacturing machine that includes at least one additive manufacturing tool. The system further includes a computer numerical control (CNC) controller operatively associated with the manufacturing machine and configured to control the at least one additive manufacturing tool based on computer aided manufacturing (CAM) instructions. The system further includes a CAM controller operatively associated with the CNC controller and configured to determine the CAM instructions based on computer aided drafting (CAD) instructions, the CAM instructions including a plurality of CAM operation control functions, each of the plurality of CAM operation control functions correlated with at least one of a plurality of CAD operation control functions of the CAD instructions.

Systems and methods for using smart models in manufacturing

A method of grind hardening a workpiece is provided. The method may include securing the workpiece in a workpiece retainer and a grind tool in a tool retainer, rotating the grind tool in a first angular direction at a first angular speed, controlling the workpiece and tool retainers such that the grind tool engages the workpiece, and controlling the workpiece and tool retainers such that the grind tool is guided along a grinding track of the workpiece. The grind tool may engage and/or disengage the workpiece at portions of sacrificial material disposed thereon. Coolant and cleaning nozzles may be provided and controlled such that at least a portion of the coolant from the coolant nozzle is diverted to the cleaning nozzle in a manner which reduces heat dissipation, improves thermal efficiency of the grind hardening and reduces loading of the grind tool.

Grind hardening method

An apparatus for obtaining information about a workpiece may include a measuring device having a nozzle defining an orifice in fluid communication with a source of incompressible fluid. A fluid monitoring apparatus may monitor a parameter of the substantially incompressible fluid, and a pump may be fluidly coupled to the source and configured to supply incompressible fluid to the orifice. The pump may have a pump chamber with a first displacement setting having a first fixed volume, so that operation of the pump at a first pump speed with the pump chamber in the first displacement setting generates a first fluid flow having a substantially constant first volumetric rate. The pump may have more than one displacement setting, or the pump may be operated at different speeds to change the volumetric flow rate. The nozzle may include multiple, independent orifice sets that may be selectively provided fluid, thereby to obtain information on different parts of the workpiece with a single placement of the nozzle. Additionally, the apparatus may be incorporated into a CNC machine to perform simultaneous measurement and machining operations.

Measuring apparatus and method

A cutting insert rotated about its axis may be utilized during a metalworking operation and applied against the rotating workpiece to enhance tool performance. The cutting insert is secured within a toolholder having features to secure the insert but at the same time make for efficient removal of the insert from the toolholder.
