The present disclosure relates to an apparatus and a method for inputting a processing shape using an interactive program in a computer numerical control machine tool, and particularly, to an apparatus and a method which are capable of more easily and conveniently inputting a shape of a work piece to be processed.
Recently, a request for an interactive program, which allows a user to conveniently input a shape and a processing condition of a work piece and create a processing program in a work field, is being increased. However, in a method of inputting a shape of the interactive program of the related art, a user defines a shape by sequentially inputting only straight line and circular arc elements that are provided by the interactive program while seeing the drawings. In this method, it is difficult and inconvenient to input a shape. In addition, the user needs to input a shape every time in accordance with contents of work, and in order to reuse contents of past work, the user needs to select the corresponding contents of work or shape information, and performs entire or partial correction thereof.
In some exclusive processing apparatuses, information on frequent contents of work is patterned and provided by a system, but the exclusive processing apparatuses is limited to a restrictive shape for a specific processing or a standardized processing, and is not used for a processing for a turning center (TC). In addition, in order to increase convenience for the user in inputting a shape, some interactive programs provide a function of inputting a shape using a CAD file. However, because this function changes the CAD file made by the user into internal data of the interactive program, reutilization of the existing processed shape information is very low.
In addition, there is a case in which an expert user directly makes a macro program using variables in a memory in a machine tool, but the expert user needs to participate in working for a long period of time, and an environment for convenience of use is not provided.
Meanwhile, for a small quantity batch production, which is gradually increased in an industrial field, it is necessary to frequently input a shape for various products, and to this end, much effort and time are needed with the method of inputting a shape using the existing interactive program. Therefore, in order to increase efficiency of a processing program in a work field, and improve convenience of the user and contents of work, an improvement in a method of inputting a shape in a processing program is acutely required.
The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter.
This summary and the abstract are provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. The summary and the abstract are not intended to identify key features or essential features of the claimed subject matter, nor are they intended to be used as an aid in determining the scope of the claimed subject matter.

As a meaning of dictionary, an interactive program mentioned in the present disclosure refers to a program which processes data by directly receiving data from a user, and means a program capable of performing an interaction with the user by allowing the user to directly participate in inputting and processing data.
In an embodiment of the present disclosure, the user may register an arbitrary shape in an interactive program as a user registration shape, and may store a shape being processed or having been processed presently or a shape processed in the past in the interactive program as the user registration shape as necessary without other separate programming procedures.
Hereinafter, an apparatus and a method for inputting a processing shape using an interactive program in a computer numerical control machine tool according to an exemplary embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

The shape information list 120 outputs shape elements such as a start point, a straight line, a circular arc, a round, a chamfer, and the like of the shape inputted by the user, and coordinate information of the respective shape elements, as a list type. Here, each column of the shape information list 120 may be selected by the user. Therefore, the user may easily select the shape element that is being processed, and may correct or delete the selected shape element.
The shape element selection part 130 may select the shape element by designating a corresponding block on a touch screen, and may be implemented to enable a selective input by a manipulation of an input unit (520 in
Referring to
The user registration shape output part 210 shows shape graphic information processed by the user, together with the shape element that is selected by the user in order to set a parameter.
The variable definition part 220 provides a variable list of the selected shape element, and may receive variables including a length L1 for each position P1, a position coordinate X1 and Z1, an element start point, and an angle between elements of the shape element which is selected by the user through the variable list. Therefore, the user may allocate the shape of which a parameter setting is completed to an internal variable of the interactive program through the variable definition part 220.
After the parameter setting of the shape is completed, the interactive program produces a macro NC code which defines the shape of which a parameter setting is completed as the variable, and stores graphic information, a parameter, and the macro NC code of the shape in an internal memory to register the shape of which the parameter setting is completed in the internal memory as the user registration shape.

The user registration shape list 310 shows a plurality of user registration shapes stored in the interactive program. The user registration shape list 310 may switch the screen by using arrows 312 at the left and right sides in accordance with the number of user registration shapes. Therefore, the user may select a shape, which is similar to a shape to be presently processed among the plurality of user registration shapes through the shape graphic information outputted from the user registration shape list 310.

That is, the display unit 530 registers a shape processed by the user as the user registration shape, and provides a user interface environment capable of loading and editing the registered user registration shape.
The memory unit 540 stores a control program for controlling the entire operations of the system through the processor 510 and the interactive program which is necessary to drive the machine tool 550.
In addition, the memory unit 540 according to the present disclosure stores the user registration shape registered by the user. In detail, the memory unit 540 stores graphic information, a parameter, and a macro NC code of the shape inputted by the user so as to store the inputted shape as the user registration shape.
In addition, at the time of a user request, the memory unit 540 may provide the stored user registration shape to the user through the display unit 530. Here, the memory unit 540 may provide a parameter corresponding to the user registration shape, together with the user registration shape.
The interactive program control unit 560 generally controls an operation of the machine tool 550, provides a plurality of user registration shapes stored in the memory unit 540 through the display unit 530 when the user requests the user registration shape, and after the user selects a representative shape from the plurality of user registration shapes and inputs a parameter of the selected representative shape, outputs the shape information corresponding to the parameter, and transmits the outputted shape information to the PMC unit 570.
The PMC unit 570 drives the machine tool 550 on the basis of the shape information received from the interactive program control unit 560.
Therefore, the user registers a shape, which has been already processed by the user, in the interactive program as the user registration shape, selects a shape, which is similar to a shape to be presently processed among the plurality of user registration shapes, at the time of performing new processing, and changes only a parameter of the selected user registration shape, and as a result, efficiency of inputting a processing shape may be increased, and convenience of use may be maximized.
