A numerical controller includes an activation unit that builds a memory map according to settings when the power is on; a change detection unit that detects an operation requiring reconstructing of the memory map; a task control unit that, when the operation is detected, performs a stopping process of a task being operated; and a memory map control unit that, after the task has stopped, acquires a backed up memory, reconstructs the memory map according to the setting, and compares the reconstructed memory map and the backed-up memory map, and resets information required for operating the task again such as a program counter.

The method can include measuring the tridimensional positions of a reference feature for a first at least three different angular positions of the reference feature around the first rotation axis and a same first reference angular position around the second rotation axis, the reference feature being fixed relative to the component; and measuring the tridimensional positions of the reference feature for a second at least three different angular positions of the reference feature around the first rotation axis and a same second reference angular position around the second rotation axis.

A method and apparatus for generating machining code of workpieces from a paper engineering drawing are provided. The method includes processing the paper engineering drawing to be a binary image; extracting dimension features and shape features of the workpieces from the binary image; and generating the machining codes of the workpieces based on the extracted dimension features and shape features of the workpieces. The machining codes indicate the dimension and shape of the workpieces, Machining codes of workpieces are generated from a paper engineering drawing directly without manual involvement.

A method for manufacturing a three-dimensional object includes converting model data of the three-dimensional object into slice data, sintering powder based on the slice data after the conversion, and manufacturing the three-dimensional object by a layered manufacturing process of stacking a plurality of sintered layers. The method includes a part data correction process of correcting positional information of at least one of mutually adjoining part data of the model data of the three-dimensional object, and laying part data on each other by a predetermined amount of overlap, converting the model data corrected in the part data correction process into slice data, and after forming a sintered layer based on the slice data corresponding to one part, forming a sintered layer based on the slice data corresponding to the other part.

A numerical controller enabling prediction of a machining time considering a machine delay occurring in a machine. The numerical controller configured for predicting a reference machining time corresponding to a machining time not considering acceleration/deceleration of an predicting the number of times of acceleration/deceleration of the axis in machining storing information related to a deviation time corresponding to a difference between an actual machining time corresponding to a machining time required for actual machining by the machine and the reference machining time predicted in the machining, calculating a correction time for correcting the reference machining time based on the number of times of acceleration/deceleration predicted and the information related to the deviation time stored, and calculating a predicted machining time obtained by correcting the reference machining time using the correction time.

Devices and methods to extract a desired product from organic matter using supercritical fluid extraction processes are described herein. The extraction vessel generally includes a reaction chamber, a water jacket affixed to the reaction chamber capable of separate pressurization, and a closure mechanism with a gasket, a plug, and a cap ring with ACME threading. The extraction vessel may be sealed by hand closure without a need for additional tools to create a seal able to withstand pressures up to 5,000 psi.

A controller capable of preventing human mistakes by customizing checking contents upon operations of users to automatically perform customized checking appropriately is provided. A controller that controls an industrial machine includes: a receiving unit that receives a condition of a callback process associated with control of the industrial machine and an action corresponding to the condition; and a designated condition registering unit that registers the condition and the action received by the receiving unit as a callback process.
