A method includes disposing an intervention service tool within a tubular. The intervention service tool includes an anchoring system, a shifting system, and a linear actuator system. The tubular includes a shifting profile geometry disposed within the tubular at a first location. The anchoring system, the shifting system, and/or the linear actuator system is actuated. Shifter system pressure, linear actuator system force/pressure, and displacement of the shifting system is measured. A known graph of the shifting profile geometry is compared to one or more of a measured pressure, a measured force, or a measured displacement. A position of a key disposed on the shifting system is determined relative to the shifting profile. The shifting profile geometry is engaged with the key based on the position of the key. The shifting profile geometry is positioned at a second location that is different from the first location.

A first drive operates directly on a machine element, whereas a second drive operates on a machine element via a speed-changing device. A position controller receives a position setpoint value and a position actual value of the machine element and determines therefrom a speed setpoint value for the machine element. A first determining device receives the speed setpoint value and determines a resulting speed setpoint value using the speed setpoint value. A first speed controller determines a first force setpoint value from the resulting speed setpoint value and the speed actual value of the machine element and controls the first drive depending on the first force setpoint value. A second speed controller determines a second force setpoint value from the resulting speed setpoint value and the speed actual value of the second drive and controls the second drive depending on the force setpoint value.

The control unit maintains an interval between the first and second encoder heads to be constant, and moves the first and second bases while sequentially detects a first and second graduation numbers, and calculates a distance on the scale between the first and second encoder heads by multiplying a difference between the first and second graduation numbers by the pitch, and calculates a position correction coefficient of the scale as a ratio of the interval with respect to the calculated distance, and controls the movement amount of the first movable body and the second movable body based on the position correction coefficient.

An operation of a processing machine with redundant actuators is controlled according to a reference trajectory by selecting, from a set of points forming a segment of the reference trajectory to be processed for a period of time, a subset of points corresponding to a fraction of the period of time. The subset of points is selected such that the redundant actuators are capable to position the worktool at each point in the subset within the period of time and are capable to maintain the worktool at the last point of the subset after the period of time while satisfying constraints on motion of the redundant actuators. The segment of the reference trajectory is modified in the time domain and the control inputs for controlling the motion of the redundant actuators are determined using the modified segment of the reference trajectory.

A virtual object is displayed with a simple method. A graph generation portion generates, as the machine configuration of a control target, a graph in which constituent elements including a camera are nodes, a node selection portion selects a node on which a virtual object is desired to be displayed, a selection node notification portion notifies the node on which the virtual object is desired to be displayed to a machine configuration management device, a transformation information calculation portion calculates transformation information which includes, as a variable, a coordinate value of a control axis node on a path in the graph from a camera node to the node of a display target and which is used for calculating the position and/or the posture of the node of the display target in a coordinate system of the camera node based on the graph, a transformation information notification portion notifies the transformation information to an augmented information controller and a coordinate information transformation portion transforms the coordinate value of a control axis which is notified into the position and/or the posture of the node of the display target in the coordinate system of the camera node.

A method of toolpath generation is provided whereby the tool may be any smooth convex axisymmetric shape. The tool includes a tool body extending between a shank and a head. The shank is configured to be mounted in a collet which may optionally rotate. In the case of a stylus tool, the head has an axisymmetric forming surface used to press metal. In the case of a routing tool, the head has cutting surfaces which are enveloped by a smooth convex axisymmetric surface and the tool is used for milling a part. In a least one embodiment the tool is a stylus tool which has a forming surface that has been generated from a portion of a clothoid curve.

An anomaly detection device of a machine tool includes a time series data acquisition section for acquiring target time series data that is the time series data of a moving load in the Z-axis direction of a cutting tool of the machine tool during a drilling process, an evaluation value derivation section for deriving an evaluation value indicating a degree of similarity between at least a part of the acquired target time series data and at least a part of reference time series data that is time series data of the moving load that can be regarded as normal using singular spectrum transformation, and an anomaly determination section for determining the presence or absence of an anomaly of the machine tool based on the derived evaluation value.

A lathe capable of shortening a cycle time of workpiece machining. A lathe includes a first spindle, a second spindle opposite the first spindle, a tool post on which a cut-off tool is provided, and a control unit which controls rotation of the first and the second spindles and further controls relative movement of the first and the second spindles and the tool post to cut-off the workpiece. The control unit adds a rotation speed fluctuation to a rotation speed of the first spindle after rotating the first spindle and the second spindle synchronously and detects a rotation speed of the second spindle. The control unit determines that the workpiece is normally cut-off upon determining that a detected fluctuation in the rotation speed of the second spindle is within a predetermined range.
