This lightweight and practical, four component dynamometer measures the cutting forces in any drilling process. The measured values can be read on the internal display or on a large external display using auto-hold. The PC-based data acquisition is performed over the built-in USB interface with the included software for tool dynamometers. Over the same interface the device parameter setup for wear detection is executed. After the setup, the device is able to supervise a drilling process without a connected PC. With this great properties the device suits multiple educational and industrial applications.

Measuring range:

Axial force Ff: pressing & pulling +/- 5000 N
Axial torque M: Right & left hand rotation +/- 30 Nm
Data Acquisition with TeLC Windows software sampling rate adjustable 5 - 100Hz

Experiments:

The cutting forces of the drilling process is measured on the workpiece which is clamped to the head of the device. Usually, this is a bar with a 40x20 mm (1.63" x 0.82") cross-section. The device itself is bolted onto the machine table. The measuring range is suitable for drilling with drills of about 15mm (0.6") diameter and feeds up to appr. 0,3mm/rev. The device is protected against liquids. The following experiments are possible:

• Examination of the influence of cutting geometry, material, lubricant coolant and machine settings
• Determination of the optimum parameters of a drilling process
• Investigation of any thread-cutting process (especially negative torque)
• Investigation of the pulling-effect occuring with some materials or drill geometries
