Abstract: A numerical controller carries out acceleration/deceleration control over an interpolation pulse produced based on command blocks. This numerical controller exercises acceleration/deceleration control processing over the interpolation pulse based on an acceleration/deceleration setting which corresponds to the command blocks, and outputs a first speed pulse. The numerical controller exercises acceleration/deceleration control processing over the first speed pulse such that command blocks overlap each other, based on an overlapping shared acceleration/deceleration setting which does not depended on the command blocks, and outputs a second speed pulse.

Abstract: A positional information display system includes a control device, a conversion information calculation device and an image information control device, in which the conversion information calculation device has a conversion information calculation portion which calculates conversion information representing a position and/or posture of a first coordinate system on a second coordinate system with a coordinate value of each axis of an industrial machine as a variable; and the image information control device has a coordinate information conversion portion which calculates a position and/or posture on the second coordinate system using conversion information and a coordinate value of each axis; a positional information calculation data setting portion which sets calculation data of positional information for visually displaying the position and/or posture in the first coordinate system by the third coordinate system of a display device; and a positional information display data calculation portion which calculat

Abstract: To provide a controller capable of exerting acceleration/deceleration control more accurately than has been exerted conventionally and capable of reducing the occurrence of shock and shortening cycle time. A numerical controller outputs a movement command for a drive axis of a machine based on a command in a program for controlling the machine having the drive axis controlled by a servo motor. The numerical controller exerts acceleration/deceleration control over the drive axis so as to satisfy a condition for the acceleration/deceleration in each of a machine coordinate system as an orthogonal coordinate system in the machine and a drive axis coordinate system by normalizing each of acceleration/deceleration related information in the machine coordinate system and acceleration/deceleration related information in the drive axis coordinate system to a value in the drive axis coordinate system.

Abstract: A virtual object display system that generates, as the machine configuration of a control target, a graph including nodes, selects a node on which a virtual object is to be displayed, notifies the node on which the virtual object is to be displayed to a machine configuration management device, calculates transformation information which includes a coordinate value of a control axis node on a path in the graph from a marker 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 marker node based on the graph, notifies the transformation information to an augmented information controller and transforms the coordinate value of a control axis into the position and/or the posture of the node of the display target in the coordinate system of the marker node.

Abstract: A numerical controller has a fixed cycle operation section that analyzes a fixed cycle command and generates a command data string based on the analysis result. The fixed cycle operation section includes a remainder calculation section that calculates a remaining cutting depth based on an entire cutting depth of a tool for a workpiece and a cutting depth of the tool for the workpiece in one cut that are specified by the fixed cycle command, and a command data string adjustment section that adjusts order of command data items included in the command data string or a cutting depth in each of the command data items based on the remaining cutting depth such that the total of a feed movement amount of the tool resulting from the command data string is reduced.

Abstract: A numerical controller which controls a machine tool on the basis of a program instruction analyzes the program instruction to generate movement instruction data, and sets a value of a constant used for speed change on the basis of a physical amount regarding a curvature at a current position on a movement path based on the generated movement instruction data. Then, the numerical controller calculates movement speeds of axes of the machine tool using the set value of the constant used for the speed change, and controls the axes on the basis of the calculated movement speeds.

Abstract: A numerical controller which can freely and easily specify, as a control point, various positions on a machine configuration and which can easily set coordinate systems in places on the machine configuration. A numerical controller expresses the machine configuration of a control target in graph form where constituent elements are nodes and holds the machine configuration. The numerical controller includes: a control point coordinate system specification portion that specifies, with the identifier, one or more groups of the control point and the coordinate system; a command value determination portion that uses the specified control point and the coordinate system to determine for which control point and on which coordinate system one or more command values commanded in a program correspond to a coordinate value; and a movement command portion that commands a move of the control point such that the coordinate value of the control point is the command value.
