SINUMERIK 840D/810D Operator's Guide ManualTurn (BAM) – 08.02 Edition 2-29
2.5 Operating system
General notes
Options for manual intervention as well as step-by-step machining of
lathed parts are the principle features of turning machines controlled in
the conventional manner (X, Z; one spindle).
With the ManualTurn system, you enter travel commands in plaintext
via simple input screen forms in a graphics-assisted dialog.
The following machining modes are at your disposal:
• MANUAL
• STRAIGHT
• TAPER
• CIRCLE
• CYCLES
• STOCK REMOVAL
• CONTOUR
• PROGRAM
Machining possibilities
With ManualTurn, workpieces can be machined as follows:
• conventionally with single-cycle machining
• automated with step chain programming using EasyStep
Single cycle machining
You can parameterize the above modes (except for MANUAL and
PROGRAM) as a single cycle and process them immediately with NC
start, i.e. you can create a contour and then cut without having to
create an entire EasyStep program.
Prerequisite for single-cycle machining is that no program is selected.
An active program can be deselected by activating the "Program ON"
soft key (PROGRAM mode). The "Accept" soft key is then no longer
available in the single cycles.
Step chain programming
with EasyStep
When generating an EasyStep program, each single cycle/individual
element is created as a separate step in a machining chain (step
chain) by "accepting" the parameters.
Each step is stored on one line and consists of the entered
parameterization data with the associated element-specific icon.
The completed machining sequence can be modified later.
Once all the machining sequence parameters have been set, the NC
start key can be pressed to execute the sequence.
Under the Directory menu, PROGRAM mode offers a program
management facility in which you can store the machining sequences
you have created.
