Page 7: Introduction
Introduction Introduction Dear User, Thank you for having opted for one of our NCT100T, NCT990T, or NCT2000T control systems. It is hoped sincerely that you will be always satisfied in your work with its facilities. It should be remembered that the skill of operating the machine can only be learnt in the possession of the part programming fundamentals. -

Operator’s Panel 1 Operator’s Panel 1.1 The NC Control Panel: Display Unit and Data Input Keyboard The NC control panel employs the display unit (monitor), the softkeys beneath, and the data input keyboard. The NCT100T, NCT990T and the NCT 2000T control panels are available in different versions. - Page 9 Operator’s Panel Operator’s panel with 15" color monitor and with optional Machine control board...
- Page 10 Operator’s Panel 1.1.1 Data Input Keyboard In case of a 9" monitor directly beneath the screen are five softkeys, in case of a 15" monitor ten softkeys built together with the screen. In both cases the meaning of these softkeys can be read in the menu bars found in the bottom line of screen, therefore their meanings may alter.

Word: Address and Data A word is formed by two components: Address and data (e.g., X127.064 or Z#103). The address may comprise one or more characters (X, Z in the example), while the data may be: SQ a number that may have integer and decimal number as well (127.064 in the example) SQ expression (#103 in the example) that may contain arithmetic or logic operations on... - Page 56 Editing part programs Beginning and end of program The program begins and ends with character %. As a new program is loaded with the help of NEW action on DIRECTORY screen string %Onnnn s % is formed automatically. In the course of editing a part program on the CNC the opening and closing % characters and the program number (Onnnn) do not appear in the program list and edit field therefore they can not be altered.

Manual Reference Point Return Mode 6 Manual Operation Modes The manual operation modes are as follows: Manual reference point return Manual handle feed Incremental jog 6.1 Manual Reference Point Return Mode Reference point can be returned only upon power-on state of the machine, i.e. when there is no EMG (emergency stop) state in the rightmost field (general NC state) of status bar. - Page 67 Manual Reference Point Return Mode happened yet, symbol !! can be seen beside the position. In case the reference point has been returned on all axes REF, i.e., the caption indicating lack of reference position is cleared from the general NC state field.

After selecting the operation mode in the 2 field of status bar caption JOG appears. - Page 69 Jog Mode Note: The above discussed cases are the basic cases of jog mode. By different machines functions contrary to these may be created by the machine tool builder. It is common, for example, if pressing of a jog button is followed by the pressing of the START button, than the jog button is not to be held down any longer.

After selecting the operation mode in the 2 field of status bar caption INCR appears. - Page 71 Incremental Jog Mode Warning! If in case of greater increment sizes the jog button is left hold for a short time, the movement stops and the desired distance is not stepped by the control, this way preventing it from possible collisions!

The movement is started by acceleration and finished by deceleration. The pulse number rotated is always executed, if parameter 1373 HNDLFEED is 0 therefore, if the selected axis cannot follow the pulses coming from the manual handle those are buffered and are moved after the rotation has been stopped.

7.2.4 Calibrating Tool Offset Sensor 7.2.4 Calibrating Tool Offset Sensor The tool offset sensor calibration means the definition and storage of button positions at para- meters CONTACT. The sensor can be calibrated in two ways. The first possibility is that the button positions of the sensor are defined in a coordinate system set by the user, e.g., a coordinate system fixed to the chuck. - Page 82 7.2.4 Calibrating Tool Offset Sensor Calibrating the Sensor to the Coordinate System of Chuck The enclosed diagram beside shows the in- terpretation of CONTACT parameters.

13.3 Unconditional Restart of Automatic Operation 13.3 Unconditional Restart of Automatic Operation If automatic operation is started from interrupted state (INTD) unconditionally after START the control goes to the end position of the interrupted block and carries on machining from there. The typical applications of the function are as follows: –... - Page 104 13.3 Unconditional Restart of Automatic Operation case: in state G40 interrupting oblique linear interpolation Let us examine fragments of the following sample programs: Program No. 1: Program No. 2: N40 G90 G0 X20 Z–10 N40 G90 G0 X20 Z–10 N50 X80 Z–60 N50 G91 X60 Z–50 N60 Z–85 N60 Z–25...
- Page 105 13.3 Unconditional Restart of Automatic Operation If in the selected plane the address of one of the axes has not been programmed (e.g., Y) and movement has been made also in this direction, or in Z direction, the movement may be led back to the 1 case, i.e., the axes will move after pressing START in neither Y, nor Z direction.

To interrup- tion of axis movements outside the selected plane refer to interruption cases in state G40. case: in state G41 or G42 interrupting linear interpolation parallel to axis Let us examine fragments of the following sample programs: Program No.

13.4 Automatic Operation Restart with BLOCK RESTART Condition 13.4.3 Cases of Return by Means of BLOCK RESTART Condition Return to Block Start Position After Interrupting Simple Movement Block case: in state G40 interrupting and restarting linear interpolation The diagram shows the case, when a linear interpolation in the plane X, Z is interrupted, a manual mode is set and manual... - Page 110 13.4 Automatic Operation Restart with BLOCK RESTART Condition X=100, Y=70, Z=10. part block: Hole machining and retraction to start position (G98) or to R-point (G99). In this part block the start position is coordinate X=100, Y=70, Z=2. At the end of all three part blocks the control stops in single block mode. If the canned cycle is programmed with repetition count L the above part blocks are repeated.

13.6 Automatic Operation Start after Block Search 13.6 Automatic Operation Start after Block Search In the course of machining there may be a need for executing the program selected for auto- matic mode not from the first block, but from a block within the program. For this, the appropriate block of the program has to be pointed at. -

13.6 Automatic Operation Start after Block Search pressing key . If the number of the subprogram is not numeric, but is an arithmetic expression it will not open the subprogram. If the subprogram is called by means of repetition count (L) the cycle number from which the program is to be executed can be specified. - Page 118 13.6 Automatic Operation Start after Block Search Spindle Rotation Code: M3 The command referring to the last spindle rotation is gathered, in this case M3. Coolant Code: M8 The command referring to coolant handling is gathered, in this case M8. Other Functions: M Other M functions in the program are listed in the 2 line of the gathered information.

13.6 Automatic Operation Start after Block Search Other Intervention Possibilities Before START It is possible to change the order of execution, as well as to cancel the execution of other M codes before starting the execution of data gathered in automatic mode. The cursor can be moved along the listed commands by means of keys The cursor must be moved to the function or coordinate, the execution of which is to be taken out from the execution after the first START. - Page 120 13.6 Automatic Operation Start after Block Search key has been pressed, BLOCK SEARCH action must be pressed on VIEW screen. By the use of INTERRUPTED softkey the control starts searching for the block, the execution of which has been interrupted. Afterwards the process corresponds to that of command SEARCH.

Listing of Messages and their Codes 14 Listing of Messages and their Codes There may be two types of messages: Local and global. 14.1 Local Message Local messages are the ones connected to an action executed on a certain screen, and are not available on any other screen. - Page 122 Listing of Messages and their Codes Messages of custom macros: – error messages programmed by the user and waiting for to be canceled, or – messages programmed by the user waiting for START. In the case of global messages the different messages are needed to be answered differently, i.e., to be canceled.
