Tool Setting and Geometric Checking on Lathes and Turning Centers

People working with lathes and turning centers know about the problem of scrap parts being generated by broken or worn tools or tools which are not measured properly. It is quite common that end users or operators are not provided with the correct instruments that detect the real tool dimensions during working cycles, fundamental information for the proper execution of production.

Auto Tool Setting before, during and after the machining process enables the possibility to automatically acquire the exact values of length and diameter of different cutting tools. Tool Setters measure tools inside the machine working areas, thus in the real machining conditions. In this way tool check becomes more meaningful and faster than pre-setting outside the machine.

DESCRIPTION

Tool setters enables two fundamental measurement phases: the presetting and tool verification.

Thanks to the presetting phase, tools are measured on machine before starting the machining process, such that the axis movements provide real dimensions and not theoretical ones used in the tool dimension calculations. Furthermore, it is possible to detect and compensate thermal drift of the machine by using the software cycles.

Tool verification allows to detect cutters and drills wear or breakage between different processes, in order to keep cutting quality under control.

BENEFITS

Increase of production quality
Constant level of production quality
Time-saving in comparison with external or manual tool check
Increase of machine productivity
More accurate measurements, as they are performed in the real working conditions
Possibility to check the tools between one working phase and another
Automatic acquisition of measured values and tool table update
Facilitation of operator’s activities
Elimination of mistakes due to manual input of measurement values on CNC

VERSIONS

Marposs proposes a wide variety of tool setters and related software cycles, which cover the most different application requirements on lathes and turning centers:

Mida Arms, high positional repeatability measurement arms used for tool setting and checking on lathes. Manual, automatic or removable arms are available. The tool setter consist of a fixed base and a mobile arm and a touch probe is mounted on the mobile arm
Non-contact Tool Setting, in case you want to measure tools smaller than 1 mm and / or more complex measurements are necessary (e.g. run out, integrity check of cutter profiles)
Vision Tool Setting, ideal for micro-tools and applications requiring extraordinary metrological performances (measurement accuracy less than 2 microns). Dedicated software cycles are available for cutting tools used in turning applications on different CNC control type

Marposs also develops measurement software cycles for every tool setter type and machine configuration.
