NOTICE
Tool breakage or workpiece damage
An uncalibrated or incorrectly calibrated tool can lead to dimensional errors or to incorrect cutting values. If the values
entered are very different from the actual tool values, there is a risk that the tool may break or the mechanism or workpiece
may be damaged.
Requirement
Load the tool beforehand or enter the tool number in the "T" field. After confirming the input, a dialog will prompt you to press
the following hardkey. If this key is pressed, the tool will be changed.
Note
First approach a machine position whe
re the tool change can be performed without danger.
Operating sequence
Proceed as follows to measure the tool for the X axis of the loaded turning tool.
1. Press this softkey. The following screen appears.
2. Press this softkey.
The screen for measuring the X axis (L1) appears.
3. Check that the current tool number appears in the display fiel
d for the tool, since the calibra-
tion operation will relate to this tool.
4.
Carefully "scratch" a workpiece by an X handwheel infeed when the spindle is turning.
5. Move the slide slightly (without changing the X position) along the Z axis (longitudin
al turn-
ing) with the handwheel.
6.
Switch the spindle off.
7.
Enter the diameter measured on the workpiece in entry field "d1".
8. Accept the value by pressing this hardkey.
The controller then automatically calculates the corresponding tool offset (in the radius) and
displays this
as value "L1" in the screen form.
Programming and Operating Manual (Manual Machine Plus (MM+), Turning)
8 01/2017
9. Press this softkey.
The modified tool offset for the selected tool is applied in the X axis. Provided that the
"scratch position" in the X axis has not been moved, the measured diameter is now di
s-
played as the actual position in the position display
of the tool measurement screen.
10. Press this softkey.
The scr
een for measuring the Z axis appears.
The Z axis can be measured in the same way as the X axis.
When measuring the tool in the Z axis, you may define a distance between the workpiece
and the turning tool tip in input field "a1" to avoid surface damage on the workpiece.
11. Press this so
ftkey to return to the main screen for MM+.
Note
New offset settings lost
If you exit the screen form in step 8, the new offset will not take effect.
3.2
Limit stops
Functionality
Limit stops are used to stop the axes in a specific position.
If an axis stops in the limit stop position, it cannot be moved again until the triggering limit stop is reset.
By setting the limit stops, in the MM+ operating area, it is possible to turn simple shoulders (including tapers) without the
need for any further cycle parameterization.
Supplementary conditions
● The limit stop position is always an absolute dimension, which in turn always corresponds to the position in the absolute
actual value display on the MM+ interface. A relative limit stop position is not possible.
● A limit stop position can be entered/accepted only when the axes are stationary; otherwise, an error message appears.

3.2.2
Turning against a stop
Example:
The following example explains the operating principle of limit stops using the axis direction keys.
You can also use the handwheel to perform the machining operation.
Task
The following shoulder with a finishing allowance of 0.2 mm must be turned:
● 100 mm in the Z direction
● 50 mm final diameter in the X direction
The end face starts at 0 mm in the Z direction. The blank diameter is 70 mm.
Operating sequences for infeeding to stop
1. Position the axes in front of the workpiece (for example, X +75 mm/Z +5 mm).
2. Check the machining technology data.
3. Set the following limit stops:
– -X at 50.4 mm
– -Z at -99.8 mm (due to finishing allowance)
– +Z at +5 mm
4. Delete the limit stop for +X; it is not required.
5. Start the spindle.
6. Using the handwheel, infeed to the 1st depth of cut in the X direction.
7. Start machining in the Z axis in the negative direction using the axis direction switch.
When the limit stop position in Z -99.8 mm is reached, the Z axis stops automatically.
A message is displayed, saying that limit stop -Z is reached.
8. Switch-out the axis direction switch.
9. Using the handwheel, retract the tool from the workpiece in the X direction.
10. Using the axis direction switch and rapid traverse override, move the tool in a positive Z direction towards the workpiece
until the axis stops.
A message is displayed, saying that limit stop +Z is reached.
11. Switch-out the axis direction switch.
12. Using the handwheel, infeed to the next depth of cut in the X direction.
13. Start machining in the Z axis in the negative direction using the axis direction switch.
Repeat the procedure until the depth of rough cut is reached.
A message is displayed as the tool is fed in, saying that limit stop -X is reached.
Once this cut has been completed, adjust the limit stops to the finished dimension, provided that the axes are positioned
in front of the workpiece.
Operating sequences for adjusting to finished dimension
1. Adjust the limit stops to the finished dimension: -X to 50.0 mm/-Z to -100.0 mm
2. Using the handwheel, infeed in the X direction until a message saying that limit stop -X is reached appears.
3. Start machining in the Z axis in the negative direction using the axis direction switch.
When the limit stop position in Z -100.0 mm is reached, the Z axis stops automatically.
A message is displayed, saying that limit stop -Z is reached.
4. Switch-out the axis direction switch in the Z direction and start in the positive X direction (finishing the end face).
5. Switch-out the axis direction switch in the X direction as soon as the tool tip leaves the workpiece.

3.3
Setting the workpiece zero
Functionality
The function of setting the workpiece zero can be used to specify the reference point for machining the workpiece.
Typical application/procedure:
1. Parameterize all the machining steps (cycles) for the workpiece in relation to a "virtual zero point" (for example, an end
face).
2. Clamp the blank.
3. Scratch the relevant surface which corresponds to the "virtual zero point".
4. Use the function of setting the workpiece zero to adapt the workpiece coordinate system to the parameterized machining
operation.
Make sure that the axis does not exit from the approached position.
Additional information
The following operations are performed automatically when
you select this softkey:
•
The work offset is automatically calculated according to the current axis position in the
longitudinal axis (Z), entered in the control system memory as the basic offset and activated.
•
This will also set the position displayed for the longitudinal axis (Z) to 0.000, as this always
corresponds to the workpiece coordinate system.
•
If the workpiece zero is reset, the value "0.000" will be automatically entered in the control
system memory as the basic offset. The workpiece coordinate system display will change to
reflect this.
NOTICE
Setting the workpiece zero carefully
Setting the workpiece zero affects the absolute machining position of all machining steps that have been parameterized in
the controller. All machining steps will now be performed in relation to the zero point that has just been set.
Setting/resetting the workpiece zero without due care and attention can result in serious damage to the tool, workpiece or
machine.
Operating sequences
1. Press this softkey in the main screen for MM+.
This screen displays the currently program
med Z value of the basic work offset.

required work offset is computed automatically and stored in the appropriate place in the co
n-
trol system.
3. Press this softkey to reset t
he work offset that is currently stored on the control system. The
value "0.000" is entered in the basic offset memory location. However, all other offsets and the
active tool offset remain unchanged.

4.2.2
Machining with the handwheels
Functionality
The handwheels for the X and Z axes are not mechanically connected to the feed screws. Electronic pulse generators
mounted on the handwheels generate the information needed by the controller to execute the required traversing movement.
The handwheels are only active when the axis direction switch is in the zero position or the individual axis control keys are
disabled.
The distance traversed per handwheel pulse depends on the increment weighting setting.
Note
If the handwheel increment weighting is set t
o "0" or if the feedrate override weighting is in the "0" position, the handwheels
are disabled.
4.2.3
Setting the increment weighting for the handwheel
Functionality
Set the increment weighting from the Increment weighting machine control panel.
If you are unable to adjust the increment weighing, it will be because the controller's internal mode is incompatible with this
process.
Press the above hardkey once to resolve the problem.
NOTICE
Set increment weighing carefully
An incorrect increment weighting setting can result in damage to the workpiece, tool and machine.
4.2.4
Machining with axis direction switch
Functionality
You can move the axes in the desired direction by changing over the axis direction switch.
The feedrate at which an axis is traversed depends on the settings in the input fields for machining technology data.
The axis feedrate is also influenced by the feedrate override weighting setting and, depending on the option selected in the
input fields for machining technology data (revolutional feed/cutting speed), by the spindle override weighting.
If the above hardkey is also pressed, the axis is moved at the maximum possible speed, unless the feedrate override
weighting setting is used to specify a different value.

Note
If the feedrate override weighting is set to "0", any type of axis movement is b
locked.
With the revolutional feed and cutting speed settings, the feed is blocked until the spindle reaches the setpoint speed.
4.2.5
Spindle advance/reverse
Functionality
NOTICE
Start spindle
The spindle value should be checked before starting the spindle (for example, when changing the tool).
The last value set is active (this depends on the machinery construction of a machine manufacturer).
You start the spindle in the appropriate direction (spindle advance/reverse) by changing over the spindle direction switch:
Note
The spindle cannot be started, unless the chuck guard switch is enabled. Close the chuck guard.
NOTICE
Do not alter the chuck guard
Do not alter or adjust the chuck guard/chuck guard switch.
When the spindle is switched off, it brakes and comes to a halt. If a spindle brake is fitted, it is applied. If there is no spindle
brake or it is switched off, the spindle can be rotated freely once it has stopped.
The programmed spindle speed can be controlled by means of an appropriate spindle override switch setting (for example,
50 %).
4.2.6
Tool change
Functionality
A basic differentiation must be made between a manual and an automatic tool-changer system.
For an automatic system, the tool change is controlled by the PLC user program. The currently loaded tool is displayed in
the MM+ main screen.
For a manual system, the required tool number is manually entered from an input screen form.
Note
The following display machine data define the display:
•
MD290 CTM_POS_COORDINATE_SYSTEM
– = 0 -> Position of the tool after the turning center
– = 2 -> Position of the tool before the turning center (refer to the figure above)
•
MD1104 TOOL_CHG_MANUALMODE_MA
– = 0 -> Editing of the "T" and "D" fields is not possible, the fields are grayed out
– = 1 -> Editing of the "T" and "D" fields is possible

Acknowledge this information text using this softkey.
4. Press this hardkey.
The tool number is changed.
Please note the following for a manual tool change:
● The real tool change on the machine (tool relocation) is finished.
● The appropriate tool number (tool offset) must be communicated to the control by making a manual entry.
Note
A new tool number may be selected only if all axes and the spi
ndle are stationary.
Note
The tool number entered in the T value field must correspond to the tool loaded into the machine; otherwise, the tool will
have to be recalibrated (see also section "
Measuring tools (Page 6)"). An uncalibrated or incorrectly calibrated tool can
lead to dimensional errors or to incorrect cutting values.

3. Press this hardkey.
The value is activated.
Note
The F value (feed rate) or the S value (spindle) can only be changed if all axes and the spindle are stationary.
4.2.8
Changing the feedrate/spindle type
Changing the operating sequences feedrate type "F"
By pressing the cursor keys, you go to the display field which contains the currently programmed feedrate type (with an
orange background).
By pressing the above hardkey, you can choose one of the following feedrate types:
● Time feed (mm/min)
If time feed is selected, the axes are moved at the speed entered in this field (mm/min) (unless rapid traverse override is
activated). It can be influenced by the feedrate override switch setting.
The time feed is only possible for a constant spindle speed.
● Rotary feedrate (mm/rev)
In the "spindle speed + revolutional feedrate" or "constant cutting speed + revolutional feedrate" mode, the value entered
in this field determines the axis speed (unless rapid traverse override is activated). It is influenced directly by the feedrate
override weighting setting and indirectly by the spindle override weighting setting.
Changing the operating sequences spindle type "S"
By pressing the cursor keys, you go to the display field which contains the currently programmed spindle type (with an
orange background).
Programming and Operating Manual (Manual Machine Plus (MM+), Turning)
22 01/2017
By pressing the above hardkey, you can choose one of the following spindle types:
● Constant spindle speed (rpm)
This value defines the programmed spindle speed for machining in the "spindle speed + time feed" or "spindle speed +
revolutional feedrate" mode.
The constant spindle speed is achieved only if no speed reduction is programmed by means of spindle override
weighting or with spindle setting data.
● Constant cutting rate (m/min)
Cutting speed input value for machining in the "cutting speed + revolutional feedrate" mode. The spindle speed is
adjusted to the machining diameter of the workpiece so that uniform cutting conditions are achieved.
Since the spindle would (in simple mathematical terms) have to rotate at an "infinitely high" speed at the rotational center
point in this mode, this speed is limited in the spindle setting data by the input value "MR".
The constant cutting speed can also be influenced by means of the feedrate and spindle override weighting settings.
Note
The feedrate or spindle type can only be changed if all axes and the spindle are stationary.
4.2.9
Change the speed limitation for constant cutting rate
Change the speed limitation operating sequences
When a constant cutting rate (G96) is programmed, the maximum permissible spindle speed, corresponding to the fitted tool
chucking device, must be entered in the input field "MR" (spindle speed limitation).
WARNING
Spindle speed limitation
Failure to pay sufficient attention to this point can lead to serious damage as a result of the chucking device speed being
exceeded.

Manual machining with machining types
4.3.1
Axis-parallel traversal
Functionality
The axis-parallel traversal is used for the simple cutting on the workpiece or for positioning the axes.
If you move the axis direction switch, the control then moves the X and Z axes accordingly.
Operating sequences
1. You can access the axis
-parallel traversal function via the main screen MM+.

2. If a different machining mode is active, press this soft
key until the following mode screen is
displayed.
4.3.2
Manual taper turning
Functionality
The manual taper turning function is intended for the simple production of tapered workpieces.
For this machining type, you need to enter an angle (taper angle α). The angle input rotates the controller's internal
coordinate system according to the angle value.
When you move the axis direction switch, the controller then uses the angle input to interpolate (and simultaneously
traverses) the X and Z axes accordingly.
The programmed axis feed then applies to the path being traversed and not to the corresponding axis.
If tapers with defined end points are to be turned, the use of limit stops is a helpful addition to this function.
Note
The desired taper is traversed only by
means of an axis direction switch or axis direction keys of the machine control panel
depending on the machine equipment.
A traversal using the handwheels is not possible.
Operating sequences
1.
You can access the manual taper turning function in the main screen for MM+.

2. Press t
his softkey until the following screen is displayed.
3. The input field for the taper angle "
α" is immediately displayed with an orange background
when the machining mode is selected. You must enter the angle using the numeric keys.
A positive angle value rotates the coordinate system in traverse direction X+.
A negative angle value rotates the coordinate system in traverse direction X-.
4. The entered value is immediately accepted using this hardkey.
The taper angle remains active until you exit this machining mode by pressing this sof
tkey.
4.3.3
Manual radius turning
Functionality
The manual radius turning function is designed to simplify the machining of inside and outside radii.
The positions of the axes at the time that machining is selected form the starting point for the radii to be traversed.
When you move the axis direction switch, the control then uses the input values to interpolate (and simultaneously traverse)
the X and Z axes accordingly.
The programmed axis feed then applies to the path being traversed and not to the corresponding axis.
Note
The desired radius is traversed only by means of an axis direction switch or axis direction keys of the machine control panel
depending on the machine equipment.
A traversal using the handwheels is not possible.
