Complex processes in tool management
In the past, the CAM department provided, in addition to the NC program, other important information, such as the tools necessary and the clamping device on the program note – in paper form. From this point on, a process that was time-consuming and above all susceptible to errors started.
On the internal tool magazine of the relevant machine, the technician checked whether all of the necessary tools are available and that they are clamped in the correct holder. The protruding length required was also checked.
The technician then fetched any missing tools from the tool crib and filled the tool magazine manually. If the tool and holder combination was not in stock, the tool had to be shrunk accordingly into the holder whilst observing the correct protruding length, and be dimensioned on the presetter station. Attention of course also had to be paid to the correct tool being shrunk and dimensioned.
The measurement data from the presetter station was printed out and re-entered on the machine. When the tool was exchanged into the tool magazine, the magazine position number and tool then had to be transferred manually to the machine. It is self-evident how unproductive, but most of all how susceptible to errors, this process was in the past. An incorrect tool in the magazine or an incorrect protruding length can result in major financial loss – on the tool to machine or the tool spindle.
