Marposs’ Mida TBD non-contact tool breakage detector unit is designed to provide fast and reliable verification of tool presence or breakage inside the machine tool. The system can be used on virtually all types of machines in which tool condition has to be verified, including drill-taps, mills, HMCs, VMCs and others. According to the company, the system minimizes production time and the need to scrap and rework parts due to damaged or broken tools.
The unit works by laser beam triangulation. The laser beam is projected onto the tool surface, normally at tool breakage tolerance, and the reflected light is captured by a highly sensitive receiver. Even in the presence of coolant, tool verification cycles are said to be reliable due to an algorithm supported by dedicated electronics that accurately analyze the reflected light signal created by a rotating tool.
The unit verifies tools measuring as small as 0.0079" (0.2 mm) in diameter and rotating at speeds ranging from 200 to 5,000 rpm. It can recognize a range of solid-center tools, including drills, slot drills, taps, end mills and ballnose end mills, all with different surface treatments and colors. The system’s response time is less than 1 sec. in normal conditions with PLC modifications.
All functionality is contained within the unit’s compact housing, which can be mounted outside of the machine’s working area to save space on the table.
Also on display is the company’s Mida WRS world radio transmission touch probe; Mida Laser 75P laser tool setter; and 3D Shape Inspector software, which provides three-axis and Capps-NC five-axis on-machine measurement.
