PROSIN drill break detection as an integrated software solution for the SINUMERIK 840D control
The low-cost PROSIN software permits direct access to the current values of the digital drives of the machine tool. If a tool breaks, the current of the relevant drive changes; this value is increased in the case of a blunt tool. Additional sensors or complete monitoring electronics therefore become superfluous.
Features:
- Breakage detection for drills of 2 mm (0.08 in) or more
- Operation using SINUMERIK operator panels
- No additional hardware required
- Only one operating side
- Extremely easy to retrofit
- Up to 120 different cuts can be monitored by means of prewarning and alarm thresholds
- New: Performance value monitoring
A special screen form, which is integrated in the standard user interface of the SINUMERIK, is available for parameterizing the operations of a CNC program which require monitoring. This screen form permits input and optimization of the settings for the cuts of one or more tools to be monitored as well as display of the values that are actually measured.
The limits of the software-based monitoring solution presented here depend on the application: If collisions are to be detected, or turning/milling tools reliably monitored for breakage, the specially adapted sensor technology of other PROMETEC solutions is still required.
This tool monitoring system is of particular interest for the mass production of metal parts, e.g., in the automotive supply industry, in order to increase quality while reducing costs.
