2 Safety
Safety
Information to the user
In all applications involving the use of machine
tools or CMMs, eye protection is recommended.
Refer to the machine supplier’s operating
instructions.
The TS27R 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 HSI-C /
HSI / MI 8-4 is disconnected.
Information to the machine supplier/installer
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 literature, and to ensure
that adequate guards and safety interlocks are
provided.
If the probe fails, the probe signal may falsely
indicate a probe seated condition. Do not rely
on probe signals to halt the movement of the
machine.
Information to the equipment installer
All Renishaw equipment is designed to comply
with the relevant EU and FCC regulatory
requirements. It is the responsibility of the
equipment installer to ensure that the following
guidelines are adhered to, in order for the product
to function in accordance with these regulations:
• any interface MUST be installed in a position
away from any potential sources of electrical
noise (for example, power transformers,
servo drives);
• all 0V/ground connections should be
connected to the machine “star point” (the
“star point” is a single point return for all
equipment ground and screen cables). This
is very important and failure to adhere to this
can cause a potential difference between
grounds;
• all screens must be connected as outlined in
the user instructions;
• cables must not be routed alongside high
current sources (for example, motor power
supply cables), or be near high-speed data
lines;
• cable lengths should always be kept to a
minimum.

5TS27R probe system
Introduction
The TS27R probe is used for tool setting on CNC
machining centres.
For tool length measurements and broken tool
detection, the tool is driven against the probe’s
stylus in the Z axis. Rotating tools can be set in
the X and Y axes for tool radius offsets.
Screw adjusters allow the stylus to be aligned with
the machine’s axes.
An interface unit processes signals between the
probe and the CNC controller.

6 Operation
Achievable set-up tolerances
The tolerances to which tools can be set depend
upon the atness and parallelism of the stylus tip
setting. A value of 5 µm (0.0002 in) front to back
and side to side is easily achievable over the at
portion of the stylus tip, and 5 µm (0.0002 in)
parallelism is easily achievable with the axes of a
square tip stylus. This setting accuracy is sufcient
for the majority of tool setting applications.
Recommended rotating tool feedrates
Cutters should be rotated in reverse to the cutting
direction.
First touch – machine spindle rev/min
Rev/min for the rst move against the probe stylus
is calculated from a surface cutting speed of
60 m/min (197 ft/min).
Spindle speed should be maintained within the
range 150 rev/min to 800 rev/min and relates
to cutters of Ø24 mm to Ø127 mm (Ø0.95 in to
Ø5.0 in).
The surface cutting speed is not maintained if
cutters smaller than Ø24 mm (Ø0.95) or larger
than Ø127 mm (Ø5.0 in) are used.
First touch – machine feedrate
The feedrate (f) is calculated as follows:
f = 0.16 × rev/min f units mm/min (diameter set)
f = 0.12 × rev/min f units mm/min (length set)
Second touch – machine feedrate
800 rev/min, 4 mm/min (0.16 in/min) feedrate.
Software routines
Software routines for tool setting are available
from Renishaw for various machine controllers
and are described in the Probe software for
machine tools – programs and features data sheet
(Renishaw part no. H-2000-2298).
