| abnormal stop |
Alarm Caused Stop. An irregular means of halting a part program during the machining process. |
| activated |
A specific program that has been selected and input, so that the program can be executed. |
| alarm caused stop |
Abnormal Stop. An irregular means of halting a part program during the machining process. |
| Alarm Condition |
Any number of instances during the execution of a part program in which an error occurs, causing the control to stop the machine. |
| all erase |
A function from the program erase menu that can clear all programs from the NC directory. You must enter a formatting code to erase all. |
| background edit mode |
A mode of the control that allows an operator to create or edit a program in memory while another program is being run. |
| block |
A single line of a part program. |
| control power OFF |
A black button with an orange circle located on the Matrix display. Control power OFF is used to turn off the Matrix control. |
| conversational programming |
A process that includes a sequence of questions and programmer must answer, sometimes called "question answer format" or "prompting." Conversational programs are constructed as these questions are answered. |
| cycle start |
The control button used to begin a program or continue a program that has been previously stopped. |
| display select key |
Key on the lower left of the Matrix display that can be used to return to the main menu. Sometimes called "chapter left." |
| EIA/ISO |
A means of programming CNC machines that is standardized for use with various controllers. |
| emergency stop |
Used for emergencies only, the control button that automatically shuts down all machine functions. |
| feed hold |
The control button used to pause a program. Also known as cycle stop, feed hold pauses tool feed but does not stop spindle movement. |
| formatting code |
A password that must be entered before major changes can be made to the Matrix control, such as erasing all programs. |
| G code |
A code that determines the type of operation performed on the machine. G codes select the type of motion, speed or feed mode, etc. |
| input key |
A key located near the numeric keypad that allows you to enter data. |
| M00 |
A miscellaneous code that signals a program stop. |
| M01 |
A miscellaneous code that signals an optional program stop. |
| M02 |
A miscellaneous code that signals the end of a program. |
| M30 |
A miscellaneous code that signals a program end and rest. |
| machine door interlock |
A safety feature on Mazak lathes that automatically stops program execution if the doors are opened during operation. |
| machine setup switch |
A lockable switch on the standard controls section of the Matrix that, when enabled, allows the operator to move the turret inside the machine. |
| Mazatrol program |
A type of program unique to Mazak machines that uses conversational programming instead of G codes. Mazatrol programs can be written quickly and easily. |
| memory mode |
An automatic control mode that the Matrix must be in to execute stored programs. Memory mode is entered when the memory key is pressed. |
| menu select key |
Key on the lower right of the Matrix display that can be used to cycle through menu options. Sometimes calleds "chapter right." |
| normal stop |
A regular means of halting a part program during the machining process. |
| optional stop |
A code that pauses the program to allow the operator to inspect the machine between operations. M01 typically indicates an optional stop. |
| part program |
A series of instructions used by a CNC machine to perform the necessary sequence of operations to machine a specific workpiece. |
| program edit |
A function used to edit values within existing programs. Program edit can be used while in background edit mode, or with virtual machining. |
| program erase |
A menu that allows you to erase a specific program from the NC directory. |
| program transfer |
A function used to move programs from the NC directory to other storage devices and vice versa. |
| prove out |
To verify the accuracy of a part program. Operators use dry runs and single blocking to thoroughly check a program for errors. |
| rapid feed override selector switch |
A switch on the machine controls section of the Matrix that sets the rate at which the axis movement buttons jog the turret. |
| reset |
A key located on the keypad that stops all machine motion and places the program cursor at the top of the current program. |
| search data |
A screen within the search menu that allows you to search and find a program block. Search data can search either up or down. |
| search down |
An EIA/ISO search option that starts at the top of a program and moves down to each program block that matches the search value. |
| search up |
An EIA/ISO search option that starts at the bottom of a program and moves up to each program block that matches the search value. |
| Select Process |
A window off the Restart menu that allows you to highlight the point in a program at which you wish to restart. |
| single block |
The single block function runs the program one block at a time to prove out the program. Single block is activated by pressing the single block key on the Matrix control. |
| status light |
One of four indicator lamps on the alpha-numerical keypad that lets the operator know the status of different processes. |
| virtual machining |
A feature that generates 3-D simulations of the lathe's work area, including the tool and the part. Virtual machining is useful for proving out and editing programs. |
| Work No. |
A menu that allows you to call up a specific program by using the numeric keypad to enter a work number. |
| work number |
The number that is assigned to each program stored within the NC program directory. |
