BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a machining data display system for displaying data at a display of a numerical control apparatus (CNC) while a machining operation is being carried out, and more specifically, to a machining data display system by which machining data is selectively displayed.
BACKGROUND ART
A numerical control apparatus (CNC) is linked to a machine tool and constitutes a numerically controlled machine tool (NC machine tool), by which a complex curve or curved surface can be machined in an automatic operation mode by preprogramming a machining process. Nevertheless, the machining conditions must be constantly monitored, since an error in the machining program, damage to a tool or the like may occur even in the automatic operation. For this purpose, there is conventionally employed a machining data display system by which specific data is displayed at a display of a numerical control apparatus, to notify an operator of machining conditions. The content of the data displayed by this conventional machining data display system, however, is only the minimum data necessary for the control of a machine tool (positional data, feed speed, r.p.m. of a spindle, T code etc.) and the amount of data that can be displayed in addition to the above is limited.
Nevertheless, a wide variety of machine tools are coupled with a numerical control apparatus, and each machine tool has different specifications, machining data displayed at a display must conform with the specifications of the machine tool.
SUMMARY OF THE INVENTION
Taking the above into consideration, an object of the present invention is to provide a machining data display system capable of selectively displaying machining data inherent to a machine tool.
To solve the above problem, in accordance with the present invention, there is provided a machining data display system for displaying data at a display of a numerical control apparatus (CNC) while a machining operation is being carried out, the system comprising selecting machining data specified by a machining program from machining data registered in advance, and displaying the selected machining data at the display.
Namely, arbitrary machining data is registered in advance and the machining is carried out while each one block of a machining program is decoded and it is determined whether a command to display machining data has been output. When a command to display the machining data has been output, the stored machining data is displayed at a display in accordance with the output command.

DESCRIPTION OF THE PREFERRED EMBODIMENT
An embodiment of the present invention will be described below with reference to drawings.
FIG. 4 is a diagram illustrating a machining data definition command of a machining data display system of an embodiment of the present invention, wherein 20 designates a machining program; 30 designates a definition command for defining names of machining data, up to four names of the machining data being defined by this command, as described below; 31 designates a numeral value which is the definition command for the name of the machining data; 32 to 35 designate names of the machining data to be defined. Although the names of the machining data can be arbitrarily set, in this embodiment, 32 defines "tool number", 33 defin
