Clamping A Blank - Siemens SINUMERIK 828D Commissioning Manual

Simulation and simultaneous recording

6.4 Clamping a blank

Example: Activating the tailstock representation in the spindle chuck data
Procedure:
1. Make the tailstock visible by making the selection in the program.
2. Specify the tailstock dimensions:
Select in the operating area "Parameters" → "Setting data" → "Spindle chuck data", and
enter the "ZR" and "XR" parameters for the tailstock length and tailstock diameter.
The tailstock dimensions are written into the following machine data:
Activating the machining time display
Timers are provided as system variables in the Program runtime function. While the NC-
specific timers are always activated (for time measurements since the last controller power-
up), the channel-specific timers must be started via the following channel-specific machine
data.

6.4 Clamping a blank
The blank clamping function allows you to select and specify in more detail the clamping
location for the blank.
You require this function if your machine satisfies one or more of the following requirements:

The tailstock becomes visible if selected in the "tailstock" program.
MD53240 $MAS_ SPINDLE_PARAMETER[i]
[0]: Chuck dimension
[1]: Stop dimension
[2]: Jaw dimensions
MD53241 $MAS_ SPINDLE_CHUCK_TYPE
0 = clamp from the outside
1 = clamp from the inside
MD53242 $MAS_TAILSTOCK_PARAMETER[i]
[0]: Tailstock dimension
[1]: Tailstock length
The measurement of the total runtime for all part programs is active
($AC_OPERATING_TIME).
The measurement of the actual program runtime is active
($AC_CYCLE_TIME).
Measurement also during active dry run feedrate.
Measurement also during program test.
