発が強く望まれていた。 Conventionally, when milling is performed on this type of machine tool, a programmer must determine the machining conditions such as the tool path required to obtain the required machining shape, create a program, and input it into the machine tool. However, determining machining conditions such as tool paths required specialized knowledge and a skilled programmer. In particular, recently, operators can directly connect machine tools without going through programmers.
A machining method has been proposed in which machining units classified based on the machining shape are input, and the machine tool creates and executes a machining program based on the input machining units. Since determining the machining conditions places an excessive burden on the operator, there has been a strong desire to develop a machining control device that reduces the burden on the operator.

PATである。 Since the numerically controlled machine tool has the above configuration, first, the main controller 2 inputs the machining mode from the machining mode deployment memory 12 via the input control unit 7.
Read MODE and display it on display 9. In other words, milling is classified into a line machining mode using tools such as an end mill and a surface machining mode using tools such as a face mill, as shown in Figure 2, based on the machining shape. Referring to the final machining shape shown above, it is determined to which machining mode the machining to be performed belongs, and inputted from the keyboard 10. When the machining mode MODE is input, the control unit 7
reads the machining unit belonging to the input machining mode MODE from the machining unit development memory 13 and displays it. In the development memory 13, each machining mode MODE is classified and stored in a plurality of machining units according to the shape to be machined by milling, that is, the type of linear shape and surface shape, as shown in Fig. 2. (The machining contents of each machining unit are shown in Fig. 3.) Therefore, the operator refers to the machining unit name and manufacturing drawing displayed on the display 9 and selects the machining unit to be executed from the keyboard 10. input. Then, the control section 7
reads the machining condition items KJ such as tool movement amount, depth of cut, chamfering amount, finishing degree, etc. required for machining the input machining unit from the machining shape development memory 15, displays them on the display 9, and provides specific information to the operator. Prompts you to input the processing data DATA. The expansion memory 15 stores machining conditions KJ necessary for machining in each machining unit, and once a machining unit is specified, the machining condition items KJ necessary for the machining can be immediately read out. The operator inputs specific numerical values and the like for each item KJ displayed on the display 9 as machining data DATA while referring to the final machining shape shown in the manufacturing drawing. On the other hand, the tool path calculation control section 3 searches the machining pattern memory 11 based on the name of the machining unit, and determines what path the tool should take when executing the machining unit. That is, as shown in FIG. 3, the pattern memory 1 contains machining patterns corresponding to each machining unit.
PAT is stored. Each machining unit is based on the shape of the workpiece created by the type of tool used for machining by the machining unit and the tool trajectory created by moving the tool relative to the workpiece. For example, line center machining unit A1 processes tool center CR,
This is a machining pattern PAT that moves in a manner consistent with the path PASS that connects the start point SPT and end point FPT input by the operator.

の提供が可能となる。 As explained above, according to the present invention, in a numerically controlled machine tool that performs milling processing, the first processing unit that stores a plurality of processing units in which milling processing contents are classified according to the type of linear shape and surface shape. a second memory means which is provided with a memory means and stores the machining unit as a machining shape of a tool for machining the workpiece into a linear or planar shape and a tool trajectory of the workpiece created by the movement of the tool; and an input means for inputting numerical data corresponding to the final machined shape of the workpiece, and machining conditions for determining machining conditions corresponding to each machining tool based on the numerical data input from the input means. Since a determining means is provided and the workpiece is machined based on the determined machining conditions, the operator can determine the tool path etc. by inputting numerical data corresponding to the final machining shape of the workpiece to be machined. It is possible to provide a processing control device for milling processing in which various processing conditions including the following are calculated and determined, and there is no need for programmers and operators to determine various processing conditions one by one.
