8.15 Before milling
Every time before starting to mill:
•
Check the milling unit for visible defects and ensure integrity
•
Make sure that all covers and safety equipment are installed and
functioning perfectly
•
Make sure that all plug-in connections are securely seated
•
Check the ambient temperature; this should correspond with the
information provided in the technical data
•
Make sure the EMERGENCY STOP switch is not latched
•
Make sure that all necessary accessories (e.g. extraction system) are
correctly connected and ready for operation
•
Make sure that milling units with a coolant system have sufficient cooling
liquid in the coolant tank and that the filters/screens are clean
•
Check that the tools required are in the milling unit’s tool changer and
that the assignment corresponds with the assignment in the control
software
•
Check the milling unit interior for any loose parts and tools lying around
•
Check the alignment and correct fastening of the workpiece
•
Ensure that successful referencing of the milling unit has taken place
8.16 Process description
The templates for components to be milled are transferred as an STL file to
the Planmeca PlanCAM software. The components are positioned in a blank
in the Planmeca PlanCAM. Subsequently, settings such as process speed,
insertion depth of the milling cutter, milling sequence and scaling are
automatically specified for further processing. The Planmeca PlanCAM
generates the milling paths and calculates a milling file. The completed
milling file is saved to the control PC of the milling unit in the folder
C:\NC_Daten\Planmeca Plan Mill 50 S
. The control software
processes this information and controls the milling unit.
8.17 Milling file identifiers
After processing the work-piece to be produced in the Planmeca PlanCAM
software, a file is created with the ending
.iso
.
This file contains all relevant data that is required for executing the milling
process. The created file name contains the date and time of creation. Once
the file has loaded, the milling can be started by selecting Open milling
program and pressing the Start button in the control software.
8.18 Milling
Before starting a milling program make yourself familiar with the basic
operation of the unit (see section "Operating milling unit" on page 44) and
the software (see section "Control software" on page 63).
Make sure to comply with the safety precautions (see section "For your
safety" on page 9).
Follow these steps to start milling:
1. Make sure that a successful referencing of the unit has been performed.
