Tool shank point and tool set point
The tool set point E serves as the reference point for the length and radius values determined on the tool presetter.
The control uses the tool shank point N as the origin of the defined length and radius values.
If tool measurement is performed outside the machine, these points at the tool holder and spindle will have an enormous impact on the subsequent machining process. After a tool change, if these points do not coincide, then either too much or too little material will be removed.
Tip
So if possible measure the tools directly in the machine or using a tool presetter that has to be calibrated specifically for each machine.
Tool measurement
- Measurement types:
- By scratching or with a measuring standard in the machine
- By using a tool touch probe or a toolsetter in the machine
- By using a laser touch probe in the machine
- By using a tool presetter outside the machine
Tool touch probe
The TT touch probe is mounted insid the machine. It allows tool measurements directly in the machine.
- Characteristics:
- Measurement by means of direct contact
- Stationary or rotating tool
- Individual or overall cutting edge measurement
- Wear and breakage check
Laser touch probe
The non-contacting TL touch probe is mounted inside the machine. It allows tool measurements directly in the machine.
- Characteristics:
- Contact-free measurement
- Stationary or rotating tool
- Accounting for the spindle by measurement at rated speed
- Individual or overall cutting edge measurement
- Measurement of forming tools
- Creation of compensation value tables, e.g. multiple radius values for a spherical cutter (depends on the inclination angle)
- Wear and breakage check even during the program run
Tip
The laser-type measuring device enables you to also measure very small and fragile tools.
The milling process
For the various milling processes and machining strategies, different tools, such as roughing or finishing cutters, are required.
- Examples:
- Face milling
- Circular milling
- Helical milling
- Hob milling
- Profile milling
The control supports the definition of different tool types based on corresponding columns in the tool table.
