If you want to copy a geometry program or complete program from a
network drive to the control, you must always use an Ethernet
connection. The data transfer rate of the serial interface (RS232,
V.24) is too low for the transfer of very large part programs.
The CAM system already takes the tool geometry into account when
the geometry program is created. The tool path calculated refers
either to the tool tip or the tool center. This means that, to determine
the length of the tool, you must user the same reference point as the
CAM system (tool tip or tool center).
If you use a ShopMill function to measure your tools, the tool length
refers to the tool tip. On the other hand, if the tool center is taken into
account in calculation of the tool path in the CAM system, you must
subtract the radius of the tool from the tool length in the tool list.
Entry of the tool diameter in the tool list is not relevant to the
processing of mold-making programs. However, you should still enter
the tool diameter in the tool list for information.
