Tool setting and geometric checking on wood working machines

The use of automatic tool geometry and breakage checks on CNC machines has resulted in a significant improvement in production quality.

Conditions:

When using external tool presetting, it is not possible to measure tools in their effective working conditions and it can result in errors when entering data manually into the CNC. Furthermore, external measurement systems cannot be used to check tools wearness and their cutting edges between one working cycle and the next. Also, the failure to detect when the tool is not properly secured in the spindle can generate rejects.

Solution:

Marposs tool setters can be used to determine the dimensions of unknown tools. Typical operations include: length, radius, cutting edge wear evaluation, breakage detection and checking correct secured tool in the spindle after tool change. These are performed automatically on the machine, writing the measured data to the tool table. These operations are made possible by synergic use of Marposs hardware devices and software cycles.

• Contact tool setters are compact tool setting applications for wood cutting machines. They use dedicated measurement software to check tool integrity, measure tool length and diameter, correct for tool wear and detect tool breakages. Our applications can be installed on the following types of machine: Drilling machines, Hardware insertion centres, Edge treatment centres, Machining centres, Automatic moulders, Angular and linear machining centres for doors and windows, Automatic tenoners.
• Non contact tool setters, with laser technology, can be used together with dedicated measurement software, including disk milling cycles, to check a wide range of tools. This is the most accurate and flexible product in the Marposs tool setting range and permits the operator to inspect tools at normal machining speeds and control the integrity of the cutting edges.

Benefits:

• Increased machine productivity
• Reduced time lost due to manual presetting
• Tools can be inspected between processes
• Reduced rejects and machine down time
