Second, this key will clear the look-ahead buffer and stop execution of the program. First, while editing CNC programs, this key will return the cursor to the beginning of the program. On most controls, this button usually serves three basic functions. These keys allow program entry and modification. #Cnc screen display function verification#The most common example is during the verification of a new program. There are many times when a program stored in the control's memory must be altered. Cursor control keys (usually in the form of arrows) allow the operator to position the cursor to the desired location on the display screen. It is at the current position of the cursor that data will be entered. The prompt cursor usually appears as a blinking square or underlined character. The display screen of the CNC control will often show a prompt cursor that indicates the current entry position. Examples of when this key is pressed include entering offsets and setting parameters. This key is pressed to actually enter data. Normally located close to the letter keypad, most CNC controls have number keys positioned in much the same way as on the keypad of an electronic calculator. #Cnc screen display function full#On others, the full character set (A through Z) is available. Some CNC control panels allow only those alpha keys (N, G, X, and so on) needed for CNC programming on the keyboard. This keypad allows alphabetical character entry. Along with the cursor control buttons, the operator can use this button to find and change offsets in memory. This display screen selector button allows the user to display and manipulate the tool offsets. This key is pressed when editing CNC programs and when monitoring programs in automatic operation. This display screen selector button allows the operator to monitor the active program in the control's memory. In this mode, the display screen shows pertinent information about where the machine is currently positioned. This selector button allows the operator to look at the machine's position display. They allow the operator to select which function of the display screen he or she wants to view. You can think of these keys as like the channel selector on a television set. Machine power is usually labelled as hydraulic on or machine ready. Once the control is on, then the machine power can be turned on. The control panel power button must be pressed first, and activates the control screen and control panel. To avoid surges, most CNC machines have at least two different power buttons, one for power to the control and another for power to the machine tool itself. #Cnc screen display function code#Consult the Applications Department of your Machine Tool Builder for confirmation of any additionally required parameters.Ĭonsider the small NC code example below. Depending upon the Machine Tool Builder, other parameters may also have to changed. This parameter is sometimes set #3111.7=1 for CNC Machines with the FANUC EZ-Guide Option installed. In order to force the page to take focus when the actual message is output, we must set Parameter #3111.7=0. The Operator must press Cycle Start to continue operation. This method behaves just like an M00 (Program Stop) as operation is halted. By specifying a Macro-B statement that uses a #3006 variable assignment along with a comment, you can output a message to the page and force that page to display, regardless of the active page display. That functionality is used via a FANUC Macro-B command and the #3006 system variable. However, this method requires the Operator to actually pay attention to the program display and to have the Optional Stop option active.Ī more effective method that requires a direct acknowledgement from the CNC Operator is available via FANUC's Custom Message functionality. This allows the operator to read the relevant information immediately after the M-Code and proceed accordingly. The typical method is simply to include multiple lines of comments placed strategically after an M00 (Program Stop) or M01 (Optional Stop). The reason is self-evident.The more information that can be included with the NC Program, the less the chance of having issues during the course of production while running the program. CNC Programmers have been using comments in NC Programs for a very long time.
