7 Operation: Executing
jobs
You control and start manufacturing with DentalCNC.
In this chapter, we will give you a brief overview. For
the complete instructions, see the documentation for
DentalCNC.
NOTICE
Damaging of the machine when using
damaged tools or blanks
If tools or blanks are damaged, parts can break off and
damage the machine during job execution.
Check the blanks and tools
age before every job execution.
When you have prepared your jobs and your machine,
you can start machining. Machining is a fully auto-
mated process and only requires your attention in case
of unexpected events.
Do not move the machine during job execu-
tion, otherwise the results may become impre-
cise.
Starting jobs
1.
Ensure the following:
You created a job on your CAM computer. It
n
has been transferred to DentalCNC.
All required tools are in the right positions in
n
the tool magazine and are neither worn nor
damaged. They have also been added to
the virtual tool magazine in DentalCNC.
The required blanks are mounted.
n
If using the blank changer, the required
n
blanks are mounted in the blank magazine
and are assigned in DentalCNC.
For wet machining: There is enough cooling
n
liquid in the cooling liquid tank.
The compressed air supply is set correctly.
n
If you wish to work with ionizer: the option

Close the working chamber door.
3.
For dry machining: If you manually control the suc-
tion device, switch it on and set it to the required
level.

4.
Start machining via the depicted icon in
DentalCNC.
Aborting machining
You can abort machining as follows:
1.
Select the depicted icon.
2.
Confirm the current message.
The following happens:
a.
Machining stops immediately.
b.
You are prompted to select whether the tool
in the spindle can be inserted safely into the
tool magazine.
3.
If you want the machine to automatically put the
tool into the tool magazine, confirm the dialog. If
you want to remove the tool manually from the
collet chuck, answer the question in the negative.
Removing the tool manually is necessary in case
that putting it into the tool magazine would
damage the tool magazine inserts. Damaging the
tool magazine inserts can, for example, occur if
you mill plastics with a blunt tool. This can cause
the material to swell and accumulate at the tool
blade until the blade diameter is too large for the
tool magazine inserts.
Depending on your choice, the spindle either
puts the tool into the tool magazine or moves into
the tool change position. In the latter case, con-
tinue with the next step.
4.
Open the working chamber door.
CAUTION
Risk of injury through fast ejected tools
As soon as the collet chuck opens, any tool in the
collet chuck may be ejected into the working
chamber very fast if you do not hold in place. The
fast ejected tool may hit and injure you.
Before
the collet chuck opens and
as
the collet chuck
place by its shank.
