Pressing this key in any operating mode switches on/off the coolant
supply.
LED lit: The coolant supply is switched on.
LED unlit: The coolant supply is switched off.
Pressing this key starts sequential tool changes (active only in "JOG"
mode).
LED lit: The machine starts sequential tool changes
LED unlit: The machine stops sequential tool changes
Pressing this key in any operating mode activates the chuck to
clamp/unclamp the workpiece.
LED lit: Activates the chuck to clamp the workpiece
LED unlit: Activates the chuck to unclamp the workpiece

Pre-defined insertion strips
Customized insertion strips
Note
Pressing this key only when the spindle stops operation.
LED lit: Activates the external chuck to clamp the workpiece inwards
LED unlit: Activates the internal chuck to clamp the workpiece outwards
Pressing this key in any operating mode advances/retracts the tailstock.
LED lit: Advances the tailstock towards the workpiece until it firmly
engages with the end of the workpiece
The MCP (machine control panel) package includes two sets (six pieces each) of pre-defined insertion strips. One set is for
the turning variant of the control system and is pre-inserted on the back of the MCP. The other set is for the milling variant of
the control system.
If your control system is of the SINUMERIK 808D ADVANCED milling variant, replace the pre-inserted strips with the millingspecific insertion strips.
The MCP package also includes an A4-sized blank plastic sheet with detachable strips. You can customize insertion strips if
the pre-defined strips can not meet your needs.
In the \examples\MCP folder of the Toolbox DVD for the SINUMERIK 808D ADVANCED, there is a symbol library file and an
insertion strip template file. To make customized insertion strips, follow the steps below:
1. Copy the desired symbols from the symbol library file to the desired locations in the insertion strip template.
2. Print the template to the A4-sized blank plastic sheet.
3. Detach the insertion strips from the blank plastic sheet.
4. Pull out the pre-inserted strips from the MCP.
5. Insert the customized strips on the back of the MCP.
This manual assumes an 808D standard machine control panel (MCP). Should you use a different MCP, the operation
may be other than described herein.

Displays messages from NC programs
The alarm number is displayed in white lettering on a red
background. The associated alarm text is shown in red lettering.
An arrow indicates that several alarms are active. The number to
the right of the arrow indicates the total number of active alarms.
When more than one alarm is active, the display scrolls through
the alarms in sequence. An acknowledgement symbol indicates
the alarm cancel criterion.
Messages from NC programs do not have numbers and appear in
green lettering.

POINT" window.
Note that axis traversing directions and axis key functions are defined by the machine manufacturer.
As a rule, a coordinate system is formed from three mutually perpendicular coordinate axes. The positive directions of the
coordinate axes are defined using the so-called "3-finger rule" of the right hand. The coordinate system is related to the
workpiece and programming takes place independently of whether the tool or the workpiece is being traversed. When
programming, it is always assumed that the tool traverses relative to the coordinate system of the workpiece, which is
intended to be stationary.
The figure below illustrates how to determine the axis directions.
The orientation of the coordinate system relative to the machine depends on the machine type. It can be rotated in different
positions.
The directions of the axes follow the "3-finger rule" of the right hand. Seen from the front of the machine, the middle finger of
the right hand points in the opposite direction to the infeed of the spindle.

For machining, the workpiece is clamped on the machine. The workpiece must be aligned such that the axes of the
workpiece coordinate system run in parallel with those of the machine. Any resulting offset of the machine zero with
reference to the workpiece zero is determined along the Z axis and entered in a data area intended for the
. In the NC program, this offset is activated during program execution, for example, using a programmed
command.
The figure below shows an example of the workpiece clamped on the machine.
The programmed work offset TRANS (Page 53) can be used to generate an offset with reference to the workpiece
coordinate system, resulting in the current workpiece coordinate system.
The control system supports a maximum of 64 tools or 128 cutting edges.

The geometries of the machining tool must be taken into consideration when you execute a part program. These are stored
as tool offset data in the tool list. Each time the tool is called, the control considers the tool offset data.
You can determine the tool offset data, including the length, radius and diameter by either measuring the tool or entering the
values in the tool list (see Section "Creating a new tool (Page 18)" for more information).
As per the actual position of the point F (the machine coordinate) and the reference point, the control system can calculate
the offset value assigned to the lengths for the X and Z axes.
