Defining monitoring sections with MONITORING SECTION (option 168)

Application

With the MONITORING SECTION function, you divide the NC program into monitoring sections for process monitoring.

Requirement

  • Process Monitoring (software option 168)

Description of function

MONITORING SECTION START is used to define the start of a new monitoring section and MONITORING SECTION STOP, to define the end of the monitoring section.

You must not nest monitoring sections.

  • If you do not define a MONITORING SECTION STOP, the control still interprets a new monitoring section for the following functions:
  • For a new MONITORING SECTION START
  • For a physical TOOL CALL
  • The control only interprets a new monitoring section for a tool call when a tool change takes place.

    Tool call by TOOL CALL

  • If you program the following syntax elements, the control displays a note:
  • Positions relative to the machine datum (e.g., M91)
  • Call of a replacement tool with M101
  • Automatic liftoff with M140
  • Repeats with variable values (e.g., CALL LBL 99 REP QR1)
  • Jump commands (e.g., FN 5)
  • Spindle-related M functions (e.g., M3)
  • New monitoring section defined by TOOL CALL
  • Monitoring section ended by PGM END

Notes on the NC program

  • If you program the following syntax elements, the control displays an error:
  • Syntax error within a monitoring section
  • Stop within the monitoring section (e.g., M0)
  • Call of an NC program within the monitoring section (e.g., PGM CALL)
  • Missing subprograms
  • End of a monitoring section precedes the start of that monitoring section
  • Multiple monitoring sections with the same contents

If an error is displayed, process monitoring cannot be used.

Notes on the NC program

Input

NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.

  • Change the following contents as needed:
  • Tools
  • Cutting parameters
  • Feed rates
  • Clearance height or safe position
  • Machine-specific positions, e.g. with M91
  • Paths of program calls

Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.

In addition, test the NC programs using the simulation before the actual program run.

 
Tip

With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.

11 MONITORING SECTION START AS "finish contour"

; Start of the monitoring section, specifying an additional name

The NC function includes the following syntax elements:

Syntax element

Meaning

MONITORING SECTION

Syntax initiator for the monitoring section of process monitoring

START or STOP

Start or end of the monitoring section

AS

Additional designation

Optional syntax element

Only when START is selected

Notes

  • The control shows the start and end of the monitoring section in the structure.
  • Settings in the Program workspace

  • End the monitoring section before the end of the program with MONITORING SECTION STOP.
  • If you do not define an end for the monitoring section, the control ends the monitoring section with END PGM.

  • Monitoring sections used for process monitoring must not overlap with the AFC sections.
  • Adaptive Feed Control (AFC, option 45)
