Productivity
Advantages of the CNC machine tool
1. The higher machining speed of the CNC machine tool as well as decreased basic, auxiliary, preparation
and finishing times on the machine increases productivity. The following factors are especially influential:
· programming directly on the machine tool with manual entries
· shared responsibility in a department responsible for work preparation for programming, materials and
tools and due entry of the data at the CNC work seat
· storing recurrent machining processes of a tool specific program in form of subprograms
· optimizing NC programs on the control
· description of the work part shapes to be machined with simple geometry entries
· automatic infeed of the tool until the required dimension has been reached
· automatic initiation of all functions of the machine and direct intervention when identifying errors or
disturbances
· automatic monitoring of the production through the CNC control (automatic measuring and testing)
· universal application of tools in tool clamping systems
· possibility to preset the tools outside of the machine tool without influencing machine run-time
2. Constant quality of the work part and less scrap.
3. Increased dimension precision of the work part through high basic precision of the machine tool
(1/1000 mm)
4. Short run-through-times through product organization and combination of split machining processes
5. Improved machine utilization and rentability
6. Improved production flexibility through machining systems and correspondingly rational production of
small lots or single work parts with high complexity
Due to the advantages mentioned above the CNC machine tools are prevalent in cutting production. The
wide application field (see figure 2) is a typical characteristic of the CNC machine tools.
