Switching the operating mode with FUNCTION MODE

Application

The control offers a FUNCTION MODE operating mode for each of the technologies milling, milling-turning and grinding. Additionally, you can use FUNCTION MODE SET to activate settings defined by the machine manufacturer (e.g., switching the traverse range).

Requirements

  • Control adapted by the machine manufacturer
  • The machine manufacturer defines which internal functions the control performs with this function. The machine manufacturer must define selection possibilities for the FUNCTION MODE SET function.

  • For FUNCTION MODE TURN, Milling/turning (software option 50)
  • For FUNCTION MODE GRIND, Jig Grinding (software option 156)

Description of function

When the operating modes are switched, the control executes a macro that defines the machine-specific settings for the specific operating mode. With the NC functions FUNCTION MODE TURN and FUNCTION MODE MILL, you can activate a machine kinematic model that the machine manufacturer has defined and saved in the macro.

If the machine manufacturer has enabled the selection of various kinematic models, then you can switch between them using the FUNCTION MODE function.

If turning mode is active, the control shows a corresponding icon in the Positions workspace.

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.

12 FUNCTION MODE TURN "AC_TURN"

; Activate turning mode with the selected kinematic model

11 FUNCTION MODE SET "Range1"

; Activate the machine manufacturer setting

Notes

 
Warning
Caution: Danger to the operator and machine!
Very high physical forces are generated during turning, for example due to high rotational speeds and heavy or unbalanced workpieces. Incorrect machining parameters, neglected unbalances or improper fixtures lead to an increased risk of accidents during machining!
  1. Clamp the workpiece in the spindle center
  2. Clamp workpiece securely
  3. Program low spindle speeds (increase as required)
  4. Limit the spindle speed (increase as required)
  5. Eliminate unbalance (calibrate)
  • In the optional machine parameter CfgModeSelect (no. 132200), the machine manufacturer defines the settings for the FUNCTION MODE SET function. If the machine manufacturer does not define the machine parameter, then FUNCTION MODE SET is not available.
  • If the Tilt working plane or TCPM functions are active, you cannot switch the operating mode.
  • The preset must be in the center of the turning spindle in turning mode.
