A method for generating a machining cutter path for a curved deep cavity surface is provided, which relates to the technical field of generation of machining cutter paths for curved deep cavity surface to solve the problems of low machining efficiency and high rejection rate of thin-walled parts with curved deep cavity surface due to complex cutter paths in the prior art. The method includes the following steps: extracting a boundary contour of a curved deep cavity surface and generating an initial cutter path; considering a machine tool limitation constraint; considering a non-interference constraint; considering a non-chattering constraint, and determining a feasible region of the cutter axis vector with the consideration of the non-chattering constraint; determining feasible region of the cutter axis vector for each cutter location point; and outputting an optimized cutter path.

The invention relates to systems for steering machine tools and in particular to systems that display information to an operator of the machine tool. Such a system comprises a manually controlled cutting tool. The system receives data that defines a model of a desired cut to be made on a workpiece by the cutting tool. The system receives further data related to the current position of the cutting tool in, at least, two dimensions. A processor generates from the received data a display. The display shows the desired cut to be made and a cutting tool icon at the current position of the cutting tool relative to the desired cut. The display also shows an indication of the current error between either the current position, or direction of travel, of the cutting tool and the desired cut. An operator does not need to look at the workpiece, a drawing and the Digital Read Out simultaneously as with existing systems.

The support device acquires locus information in which a position of a machine tool corresponding to an instruction value generated by execution of an NC program is associated with time information indicating a control time using the instruction value, and variable history information in which a value of a variable updated by execution of the sequence program is associated with time information indicating an update time The support device selects a target period in an execution period of a program, displays a portion corresponding to the target period in transition indicated by the locus information on a display device, and displays the value of the variable in the target period on the display device based on the variable history information.

The objective of the present invention is to display a correspondence relationship between a specific location in a machining program and specific position in a machining trajectory in such a way as to be immediately understandable, in a display device capable of simultaneously displaying the machining program and the machining trajectory. Acquired position data of a tool, and a character string from a machining program are saved in association with one another, a part of interest of a displayed tool machining trajectory is selected, and a program block comprising a character string from the machining program associated with the selected part of the machining trajectory is selected and is displayed on the displayed machining program, thereby making the relationship between the operation of the tool and the machining program more readily understandable.

A numerical controller performs control to rotate a turret, which holds a plurality of tools on the outer peripheral portion thereof, thereby moving one (selected tool) of the tools selected by a command to a predetermined position (selected position). The numerical controller sets and holds a partial area of the outer peripheral portion of the turret as an area (passage-prohibited area) prohibited from passing through the selected position and determines whether or not the selected tool is present in the passage-prohibited area or whether or not the passage-prohibited area passes through the selected position as the selected tool is moved to the selected position.

A method for inspecting defects of a machining path is provided. The method includes the following steps. Firstly, a contour mold with a plurality of surface nodes is generated according to a machining program code. Next, a normal vector of each surface node of the contour mold is calculated. Then, a tangent vector of a block of the machining program code corresponding to the normal vector is calculated. Afterwards, an error information is obtained according to a relation between the normal vector and the tangent vector. When the error information is greater than a predetermined value, a defect information is shown on the contour mold.
