A key on the Haas control that replaces the item highlighted by the cursor with the text in the input buffer.
A feature of the Haas control that allows an operator to edit a program in memory while another program is being run.
Computer-aided design/computer-aided manufacturing. CAD/CAM software helps programmers to design parts and generate part programs efficiently.
A key on the Haas control that deletes the item highlighted by the cursor.
A key that activates the dry run feature on the Haas control. The dry run function checks a program quickly without cutting parts.
A prove out method that executes a part program withhout any parts or cutting fluid.
Used for emergencies only, the control that automatically shuts down all machine functions.
A key used to select either Program Review or Background Edit in the MEM mode and PRGRM display of the Haas control.
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.
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.
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.
A temporary location on a computer that holds all incoming information before it continues to the CPU for processing.
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.
A part program character that conforms to the syntax, or programming format, of a CNC control.
An operation mode key that lists programs and allows an operator to select, send, receive, and delete programs.
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.
A message indicating that a program is not yet in memory the first time it is selected for background edit.
A message indicating that a program is already in memory the first time it is selected for background edit.
A part program mistake that either disrupts the machining process or renders a part program useless.
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.
A message indicating that a program has been selected for background edit a second time without stopping the running program.
A key that activates a program in the LIST PROG operator mode on the Haas control.
The display key on the Haas control that lists settings when pressed once and presents dry run information when pressed twice.
JOG HANDL TO SNGL BLK. When activated, this setting allows the operator to single step through a part program with the HANDLE.
All the necessary preparation of tooling and fixturing that occurs on the machine before a part program can be executed.
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.
A prove out method that executes a part program one block at a time at reduced feeds.
The programming format of a CNC control.
A part program mistake that occurs when an illegal character appears in a program.
An unwanted but acceptable deviation from a given dimension. Tolerances indicate the allowable difference between a physical feature and its intended design.
