Kistler has introduced the Type 9129A, a three-component system, designed to offer high-precision measurements of cutting tool machinery forces of up to 8 kN, when turning outside and inside turret lathe diameters, in support of critical manufacturing process monitoring requirements.

The modular Kistler Type 9129A system consists of a dynamometer with corrosion-resistant construction that is further impenetrable to coolants. The dynamometer is comprised of four integral three-component force sensors, the outputs of which are passed to its corresponding 9-way flange socket. The force sensors are mounted with electrical ground isolation under high preload conditions between the cover plate and two lateral base plates, a specialized mounting technique which allows for minimal temperature errors, as well as force measurements achieved with virtually no displacement. The ground isolation of the force sensors largely prevents EMI and ground loop interference from compromising measurement integrity. When used in conjunction with Kistler Type 1687B and Type 1689B connecting cables, the dynamometer is environmentally protected to IP67 standards.

Designed for direct compatibility with industry disk-type turret cutting tool machinery, the Type 9129A is further offered with machinery adapters for VDI tool holding fixtures with 30mm, 40mm and 50mm diameters; Coromant Capto C5 and C6 clamping units; direct tool holding fixtures with 20mm x 40mm or 25mm x 50mm footprint; tool holders for external turning tools measuring 20mm x 20mm or 25mm x 25mm; and tool holders for internal turning tools with 25mm, 32mm or 40mm diameters. The unique technical features and specifications of the Kistler Type 9129A allow for simultaneous measurement of the three cutting forces while turning outside and inside diameters on lathes with turret-type tool heads. In addition, as a stand-alone, the Kistler Type 9129A dynamometer is suitable as a general purpose, multi-component force measurement device, able to be mounted without accessories directly onto a flat base plate.

Recommended for use with the Kistler Type 9129A cutting force measurement system, sold separately, is the Kistler Type 2825A DynoWare, a universal data acquisition and analysis software product. The simple operation of DynoWare allows for full configuration and control of up to 28 force measurement channels via USB, RS-232C or IEEE-488, with real-time visualization of measured curves, along with evaluation and calculation functions. The software allows for acquisition and evaluation of cutting force data, along with measured data storage.
