Page 1/6 Force 4-Component Dynamometer (RCD) Rotating – for measuring cutting forces on a rotating tool 9170A_000-995e-08.19 Type 9170A... Rotating 4-component dynamometer for measuring the forces and torque on a rotating tool during cutting processes. Energy and measured values are transmitted on a non-contact basis, preventing wear.

• Cutting force measurement on the rotating tool
• 4-component measurement: Fx, Fy, Fz and Mz
• Up to max. 20 000 min–1
• Non-contact data transmission
• Internal cutting fluid supply possible
• Available for conventional machine spindle interfaces
• Tool holder with ER clamps
• High run-out and balance quality
• Complete measuring system

Description

The complete measuring system comprises a rotor, stator, con- necting cable and signal conditioner. The spindle type on the machine tool determines which rotor version is required. The piezoelectric 4-component sensor, four charge amplifiers and the digital transmission electronics are integrated into the ro- tor. It measures the radial forces F x and F y, the axial force F z and the torque Mz. Digitized measuring signals to the stator, the range selection of the charge amplifiers and the power supply are transmitted contactless. The stator is fastened to the machine tool with a gap of a few millimeters. The signal conditioner is responsible for the power supply, signal transmission and for controlling the system. Three meas- uring ranges can be selected and the measurement can be started either manually or via a serial interface. The measuring signal is an analog ±10 Volt signal. Either the DynoWare soft- ware from Kistler, or compatible data acquisition software, can be used to record the data.

Applications

A rotating dynamometer is used to measure the three ortho- gonal forces Fx, Fy and Fz, as well as the torque Mz during cut- ting production processes (milling and drilling, in particular). A rotating dynamometer enables the:

• Recording of the mechanical load during the cutting process
• Wear analysis
• Optimization of cutting parameters
• Calculation of material-specific constants (e.g. the specific cutting force)
• Optimization of tool geometry and coating
• Verification of cutting simulations The forces and the torque are measured close to the cutting edge of the tool. This allows the active force vector on single- point tools to be measured directly. Due to the newly devel- oped piezoelectric sensor located in the rotor, it is possible to record highly dynamic signals. The higher natural frequency and sampling rate, compared with the predecessor system, allows signals to be monitored during high-speed processes.

For example:

• The torque to be applied during the machining process is measured directly. This permits an accurate assessment of the condition of the tool, such as its state of wear
• The rotor of a rotating dynamometer rotates with the tool and allows the direct quantification of the mechanical load of the tool
• Thanks to the independence of workpiece mass, size and shape, the cutting force and torque can be measured on complex and cost-intensive components, e.g. structural parts of aircraft or Blisks (Blade Integrated Disc) Technical data Rotor Type 9170Axxx0 Speed, max. min–1 20 000 1) Measuring range 1, nominal Fx, Fy N –5 000 ... 5 000 2) Fz N –20 000 ... 20 000 2) Measuring range 2, nominal Fx, Fy N –2 000 ... 2 000 2) Fz N –5 000 ... 5 000 2) Measuring range 3, nominal Fx, Fy N –500 ... 500 2) Fz N –2 000 ... 2 000 2) Sensitivity range 1 Fx, Fy mV/N ≈2 Fz mV/N ≈0,5 Mz mV/N·m ≈66 Sensitivity range 2 Fx, Fy mV/N ≈5 Fz mV/N ≈2 Mz mV/N·m ≈200 Sensitivity range 3 Fx, Fy mV/N ≈20 Fz mV/N ≈5 Mz mV/N·m ≈1 000 Linearity %FSO ≤±1,0 Hysteresis %FSO ≤1,0 1) Rotors with spindle adapter DIN 69871-AD50, MAS 403 BT 50 or ANSI B5.50-50 are limited to 12 000 min–1. 2) Small spindle adapters limit the useable force range of the RCD. The rotors are calibrated in accordance with limit values (see page 4).

The rotor of the measuring system is connected to the machine spindle. This means that the coordinate system of the RCD also rotates around the vertical Z-axis. Due to the rotating coordinate system of the RCD, it is possible to directly assess the mechanical loads of the tool cutting edge.
