TOOL MONITOR

Monitor and Manage

Marposs's compact tool monitoring unit (TMU) system detects breakage, wear and missing
tools by measuring and matching the variation of power consumption in different cutting
sessions. The TMU system consists of a TMU True Power (TP) module and TMview software. It
is ideal for applications involving simple processes such as drilling, tapping and milling, large
batch production, and for installations requiring monitoring without data or process analysis.
The TMU monitors the state of the tool during the processing phases. This lets users improve
machining quality, while reducing rejects and the idle periods that would be necessary to impose on
the machine if this type of check were performed manually. The TMU TP module has been designed
to be sensitive enough to detect the slight variations in power consumption caused by small tools or
finishing processes.
The TMU TP and the TMview software have been devised with the ability to record-and
subsequently compare-machining processes of the same type. This means that it is easy to
program the TMU TP to control processes that are difficult to
monitor due to the type of timescales involved, such as tapping,
LASER
which uses small tools and fast operating speeds.

ENCODER

Connection Made

Heidenhain has introduced a series of functionally safe hollowshaft connection encoders to the manufacturing equipment
industry. Called the ECN/EQN/ERN 400 series, these rotary
encoders are useful in applications in which quick machine shutoff is required in dangerous situations.
The series features a shaft coupling that provides mechanical
fault exclusion for connection to the machine shaft. The
ECN/EQN/ERN 400s are of particular use in safety-related
applications, and are available with a blind hollow shaft or a
hollow through shaft with a choice of 10mm or 12mm diameter.
The ECN/EQN/ERN 400 hollow-shaft encoders are
offered with either the EnDat 2.2 or DRIVE-CLiQ absolute
serial interfaces or an analog 1 VPP output. Encoders using
the EnDat2.2 and Drive-CLiQ outputs will feature an internal
temperature sensor integrated in the encoder electronics, as well
as an evaluation circuit for an external temperature sensor to use
for evaluation of the motor temperature.

Metal Cutter

Jenoptik's laser cutting machine-the Jenoptik-Votan BIM-is
an ideal tool for processing metal working parts. The laser has
a repeat accuracy of up to 50 μm, and in one second it cuts a
circle or other standard contour. This allows for a shorter cycle
time.
The system concept of the Jenoptik-Votan BIM series is
based on a beam guide inside the robot. Laser sources with a
power of up to 5 kW can be used without the necessity for an
external beam guide. At the same time, the equidistant beam
path prevents the laser beam from pumping effects, ensuring
a stable beam quality.
With its metal cutting laser machine series, Jenoptik serves
the automotive industry by cutting complex car body and
structural parts, as well as hydroformed tubes that are used
for exhaust systems or car body rail manufacturing.
