Safety
Information for the user
In all applications involving the use of machine tools or CMMs, eye protection is recommended.
Remove power before performing any maintenance operations.
It is the machine supplier’s responsibility to ensure that the user is made aware of any hazards
involved in operation, including those mentioned in Renishaw product documentation, and to
ensure that adequate guards and safety interlocks are provided.
Under certain circumstances the probe signal may falsely indicate a probe seated condition. Do
not rely on probe signals to stop machine movement.
The expected method of providing an emergency stop for Renishaw products is to remove power.
Information for the machine supplier/installer
The high-precision removable arm (HPRA) system must be installed by a competent person,
observing relevant safety precautions. Before starting work, ensure that the machine tool is in
a safe condition with the power switched OFF and the power supply to the TSI 2 or TSI 2-C
disconnected.
Equipment operation
If this equipment is used in a manner not specied by the manufacturer, the protection provided by
the equipment may be impaired.

Where the RP3 is to be used in the probe’s Z-axis (the lathe Y-axis), a ve-faced stylus is available to order from
Renishaw’s Styli and Fixturing Products Division (SFPD), or from our Web shop at www.renishaw.com/shop.

Performance specication is tested at a standard test velocity of 480 mm/min (18.9 in/min) with a 35 mm stylus.
Signicantly higher velocity is possible depending on application requirements.

4
Trigger force, which is critical in some applications, is the force exerted on the stylus by the tool when the probe
triggers. The maximum force applied will occur after the trigger point (overtravel). The force value depends on related
variables including measuring speed and machine deceleration.

These are the factory settings; manual adjustment is not possible.

System installation
HPRA installation
For best performance of the HPRA, the following installation guidelines are recommended:
• The HPRA is ideally mounted on a solid xed part of the machine tool, such as a
casting. If mounting brackets or plates are used, these must be designed to maximise
stiffness with minimal joints. If mounted onto a moving part of the machine tool,
repeatability may be adversely affected.
• The HPRA is sealed to IPX8 and designed for the harsh environments inside
a machine tool. However, high-pressure jets and reected jets can exceed this
specication and must not spray directly onto the HPRA base. If it is not possible to
position the HPRA base away from these jets, the base should be protected with
suitable guarding. Guarding is not supplied by Renishaw.
• Like all metrology systems, repeatability can be adversely affected by thermal effects
on the machine tool. Renishaw recommends thermal compensation routines are
incorporated into the measurement software cycles to counteract these effects.
