ALTER |
A key on the Haas control that replaces the item highlighted by the cursor with the text in the input buffer. |
background edit |
A feature of the Haas control that allows an operator to edit a program in memory while another program is being run. |
CAD/CAM |
Computer-aided design/computer-aided manufacturing. CAD/CAM software helps programmers to design parts and generate part programs efficiently. |
DELETE |
A key on the Haas control that deletes the item highlighted by the cursor. |
DRY RUN |
A key that activates the dry run feature on the Haas control. The dry run function checks a program quickly without cutting parts. |
dry running |
A prove out method that executes a part program withhout any parts or cutting fluid. |
EMERGENCY STOP |
Used for emergencies only, the control that automatically shuts down all machine functions. |
F4 |
A key used to select either Program Review or Background Edit in the MEM mode and PRGRM display of the Haas control. |
FEED HOLD |
The control used to pause a program. FEED HOLD pauses tool feed but does not stop spindle movement. |
first part run |
The first successful execution of a part program that produces the first good part. |
graphics display |
A function of the Haas control that allows an operator to visually dry run a part program without moving the axes and risking tool damage. This prove out method is accessed by pressing SETNG/GRAPH twice. |
illegal character |
A part programming character that does not conform to the syntax, or programming format, of a CNC control. The control is not able to read or execute an illegal character. |
input buffer |
A temporary location on a computer that holds all incoming information before it continues to the CPU for processing. |
INSERT |
A key on the Haas control that inserts the text in the input buffer after the current cursor location. |
JOG HANDL TO SNGL BLK |
Setting 104. When activated, this setting allows the operator to single step through a part program with the HANDLE. |
legitimate character |
A part program character that conforms to the syntax, or programming format, of a CNC control. |
LIST PROG |
An operation mode key that lists programs and allows an operator to select, send, receive, and delete programs. |
logical error |
A part program mistake that occurs when an unintended legitimate character or value appears in a part program in place of the intended character or value. |
NEW PROG |
A message indicating that a program is not yet in memory the first time it is selected for background edit. |
PROG EXISTS |
A message indicating that a program is already in memory the first time it is selected for background edit. |
program error |
A part program mistake that either disrupts the machining process or renders a part program useless. |
proving out |
Performing a series of steps to verify the accuracy of a part program. Operators use graphic displays, dry runs, and single blocking to check a program for errors. |
SECOND EDIT |
A message indicating that a program has been selected for background edit a second time without stopping the running program. |
SELECT PROG |
A key that activates a program in the LIST PROG operator mode on the Haas control. |
SETNG/GRAPH |
The display key on the Haas control that lists settings when pressed once and presents dry run information when pressed twice. |
Setting 104 |
JOG HANDL TO SNGL BLK. When activated, this setting allows the operator to single step through a part program with the HANDLE. |
setup |
All the necessary preparation of tooling and fixturing that occurs on the machine before a part program can be executed. |
SINGLE BLOCK |
A key that activates the single block feature on the Haas control. The single block function runs the program one block at a time to prove out the program. |
single blocking |
A prove out method that executes a part program one block at a time at reduced feeds. |
syntax |
The programming format of a CNC control. |
syntax error |
A part program mistake that occurs when an illegal character appears in a program. |
tolerance |
An unwanted but acceptable deviation from a given dimension. Tolerances indicate the allowable difference between a physical feature and its intended design. |
