are in full compliance with CE standards and fulfill the

standards respecting Electromagnetic Compatibility (EMC)

(Chapter 14).

2.4 Instructions on handling the devices

2.4.1 Dynamometer

The rotating dynamometer may be installed, operated and

serviced only by persons who are familiar with the device

and who are sufficiently qualified for their respective work.

Attention!

 Mount the dynamometer in accordance with

regulations in the spindle of the machine tool.

 The maximum speed – engraved on the rotor or

specified in these instructions in Chapter 11 – may

not be exceeded.

 Only tools that have been approved by the tool

manufacturer for the corresponding speed may be

used.

 The rotating cutting force dynamometer may be

used only with the safety devices (protective doors,

etc.) that are prescribed by the tool manufacturer.

 Spindle adapters and tool adapters can be

dismantled or replaced. Prior to operation, it must

be ensured that the screws are tightened in

accordance with regulation and that balance quality

handling of mains-fed electrical and electronic devices.

 Energized parts could become exposed when the

covers are opened or components are removed while

the device is connected.

 Calibration, maintenance and repair tasks on

energized, open devices should be avoided as much as

possible. If however such tasks are unavoidable, they

may be carried out only by a technician who is familiar

3. General system description

3.1 Purpose of the rotating cutting force Dynamometer

The rotating cutting force dynamometer (RCD) is used for

the dynamic and quasi-static measurement of the three

Cartesian force components F

, F

and the torque M

a rotating tool. Data transmission is accomplished with

near field telemetry.

The dynamometer is compact in construction and has

considerable rigidity, whereby the usable frequency range

is determined by the dynamometer, the attached adapter

and tools, the machine tool and the telemetry system.

Rotating cutting force dynamometers are suitable for basic

research and application investigations of production

processes, particularly of milling and drilling processes.

In cases of critical tools and expensive workpieces, the

device can also be used to monitor the process.

Fig. 1:RCD Type 9171A… with

coordinate system

3.1.1 Application examples

The rotating cutting force dynamometer (RCD) can be

used for a wide variety of measurement tasks in the

measurement laboratory. These include, for example:

 Optimization of drilling, milling, reaming and similar

tools

 Investigation of wear mechanisms

 Determination of tool life

 Investigation of cutting processes (interactions

between tool cutting edge and workpiece)

Rotating measurement systems have the advantage over

measuring platforms (i.e. stationary dynamometers) of

measuring the cutting forces on the rotating tool

independently of workpiece weight and workpiece size.

Page 10 9171A_002-718e-01.19

3.2 Components of the measurement system

Fig. 2: RCD measurement system

The system of the rotating Dynamometer Is comprised of:

 Dynamometer (rotor) with built-in charging amplifier

and telemetry electronics (Type 9171A….)

 Stator with power supply and receiver (Type 5236B)

 Connection Cable (Type 1500A95)

 Signal Conditioner (Type 5238B…)

 Spindle adapter (only if ordered accordingly)

 Tool adapter (only if ordered accordingly)

General system description

9171A_002-718e-01.19 Page 11

3.2.1 The rotating Dynamometer

 A 4-component sensor (F

, F

, M

) is built into the

Rotating Dynamometer Type 9171A... that is built in

using a hollow expansion screw under high initial

tension between machine adapter and the tool

adapter. This is the prerequisite for the transfer of the

friction forces for the measurement of the shear forces

and F

and the torque M

 The dynamometer is corrosion-resistant and secured

against the entry of splash water and coolant (IP67).

This also applies for the stator.

 A miniature charge amplifier is built into the Rotor

(Dynamometer) for each of the 4 components (F

, F

, M

). The power supply to the amplifier is contact-

free by way of induction. The transfer of

Reset/Operate and range switching is also non-

contact.

 The output signal of the charge amplifier is digitized at

a resolution of 12 bits and transmitted.

 On the stationary side, the digital data flow is

demultiplexed in the signal conditioner (Chap. 3.2.3)

and converted back into an analog signal.

3.2.2 The stator

The Stator Type 5236B is the receiver and transmission unit

on the stationary side of the measurement system.

The transmission and receiver antenna is built into the

stator. The transmission antenna transmits the power

supply for the electronics built into the rotor and the four

control signals 'Range F

, F

1/2/3', 'Range F

1/2/3',

'Range M

1/2/3', 'Operate/Reset'.

The receiver antenna receives the data signals transmitted

from the rotor and forwards them to the signal conditioner.

The Stator Type 5236B… can be used not only for the

RCD Type 9171A… but also for the smaller RCD Type

9170A….

Rotating Cutting Force Dynamometer, Type 9171A...

Page 12 9171A_002-718e-01.19

3.2.3 The signal conditioner

The Signal Conditioner Type 5238B... is the signal

transmitter and power supply unit/control unit for the

rotating dynamometer.

The control commands (Chapter 11.3.2) can be entered

either manually by means of switches on the front panel or

via a RS-232C interface using a PC.

The serial data flow conveyed by the dynamometer is

demultiplexed, analog-converted and low pass-filtered

(Chapter 11) and made available as ±10 V signal.

The Test pushbutton represents an additional function.

If the transmission path is completely functional, then

a voltage of 5 V will be active on all measuring

channels when this button is activated (Chapter 4.12).

The Signal Conditioner Type 5238B… can be used not only

for the RCD Type 9171A… but also for the smaller RCD

Type 9170A…. The Signal Conditioner identifies the Rotor

Type used and indicates it accordingly (Chapter 4.10).

3.3 Options and accessories

3.3.1 Spindle adapter

The RCD Type 9171A… permits the replacement of the

spindle adapter and thus offers great flexibility for users

with various spindle interfaces. The spindle adapter is

mounted on a flange on the rotor for this purpose.

A wide variety of conventional spindle adapters are

available as standard. These can be ordered at any time

and independently mounted by the user when certain

stipulations are observed. Mounting and dismounting is

described in Chapter 4.2, balancing in Chapter 4.5.

As a general rule, the user has the right to produce spindle

adapters of its own and to attach them to the rotor. The

connection dimensions can be found in Chapter 3.4.

Mounting and dismounting must however proceed in

accordance with Chapter 4.2 and balancing in accordance

with Chapter 4.5.

General system description

9171A_002-718e-01.19 Page 13

In order to avoid damage to the RCD and to the

machine tool, one must proceed strictly in accordance

with the instructions (Chapter 4.2) during mounting.

3.3.2 Tool adapter

The RCD Type 9171A permits the replacement of the tool

adapter and thus offers great flexibility for users. The tool

adapter is mounted on a flange on the rotor for this

purpose.

Three collet chucks are available. These are described in the

following chapters.

As a general rule, the user has the right to attach tool

adapters of its own to the rotor. The connection

dimensions can be found in Chapter 3.4. Mounting and

dismounting must however proceed in accordance with

Chapter 4.3 and balancing in accordance with Chapter 4.5.

In order to avoid damage to the RCD and to the

machine tool, one must proceed strictly in accordance

with the instructions (Chapter 4.3) during mounting.

3.3.2.1 Collet ER

The Rotating Dynamometer Type 9171A… can be

equipped with a collet that fits ER 32 (DIN 6499/ISO

15488) or ER 40 (DIN 6499/ISO 15488). Collets that

deviate from this standard could damage the

dynamometer.

Various manufacturers offer these collets. As an alternative,

the collet ER 32 can also be ordered directly from Kistler.

Ultra-precision collets with the clamping range of

ø1 … 20 mm are offered under the designation Type

9169A…. The assembly of the collet is described in

Chapter 4.4.

Fig. 3: DIN 6499-B32 collet

The dynamometer Type 9171A... enables the utilization of

internal coolant of tools up to 70 bar. This means however

that the corresponding clamping nuts and sealing disks

have to be used, which can be obtained from specialist

dealers. We recommend the use of the clamping nuts

Hi-Q/ERC 32 (DIN 6499/ISO 15488) or Hi-Q/ERC 40

(DIN 6499/ISO 15488) from the Rego-Fix AG with the

matching sealing disks.
