DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a numerical control system for a machine tool or the like and, more particularly, to a numerical control system for displaying, on the screen of a display unit, operation information entered by an operator's panel, and for performing numerical control on the basis of the displayed operation information.
2. Description of the Related Art
A numerical control unit executes predetermined numerical control processing on the basis of numerical control program data and operation information determined or set by an operator's panel. The operation information may include:
(1) mode information for specifying operating modes for editing, memory operation, tape operation, manual input operation, jog operation, handle feed operation and the like;
(2) single block on/off information;
(3) dry run on/off information;
(4) block delete on/off information;
(5) machine lock on/off information;
(6) feed hold on/off information;
(7) reference point return on/off information;
(8) jog feed direction information;
(9) jog feed velocity and overdrive information;
(10) handle axis selection information; and
(11) handle feed magnification information.
In the prior art, all these items of operation information are fed into the numerical control unit by setting switches, or by pressing buttons, which are provided on the operator's panel located on the machine side. However, such an arrangement results in a very large number of switches and buttons and makes operation a complicated matter. This invites operator error.
Accordingly, there has recently been proposed a numerical control system as shown in FIG. 1, in which a numerical control unit NC for numerically controlling a machine tool is provided with a numerical control operator's panel MDI, in addition to a machine operator's panel, as means for entering operation information. The necessary operation information is displayed on the screen of a display unit CRT of the numerical control operator's panel MDI, and desired operation information is selected and fed into the numerical control unit NC by operating keys or a light pen.
The method of setting and entering operation information in this numerical control system will now be described in conjunction with FIGS. 2 through 5.
FIGS. 2(A) and 2(B) are examples in which operation information is displayed on the screen of the display unit CRT of the numerical control operator's panel MDI unit and the operation information is set and entered by operating keys or light pen connected to the numerical control operator's panel MDI while the display is being viewed.
In FIG. 2(A), "MODE" denotes a mode information selection line. The arrangement is such that any one operating mode can be selected from among a manual input operation (MDI), automatic operation (AUTO: tape or memory operation), editing operation (EDIT), handle operation (HNDL), jog feed operating (JOG) and zero-point return operation (ZRN). For example, to select automatic operation (AUTO), the operator manipulates a horizontal shift key and a vertical shift key to position a cursor ( ) to the left of AUTO. If this is done, the automatic operating mode will be selected. Further, "HANDLE AXIS" represents a handle feed axis selection line, "HANDLE *10" represents a handle feed magnification selection line, "RAPID OVRD" denotes a rapid-traverse override setting line, and "FEED OVRD" denotes a feed velocity override setting line. It should be noted that selection of operation information is performed as in the case of the mode selection. Specifically, desired operation information is selected by the operator positioning the cursor at the head of the item of the selection line being displayed on the screen of the display unit CRT of the numerical control operator's panel MDI. The setting of an operation quantity on each of the setting lines is performed by the operator operating a horizontal shift key to extend bar graphs SGl and SG2 to the right or left. That is, when the horizontal shift key is operated,
