Tools as performance factors
Production quality and process reliability are decisive factors that are significantly influenced
by the tools involved in the machining operations. That is why the precise measurement oftool dimensions combined with cyclic inspection for wear and breakage is so important.
A temperature-compensated tool axis is essential for long-term process stability.
HEIDENHAIN offers various solutions for tool measurement and inspection:
 Vision systems for inspection of cutting edges, for tool measurement, and fortemperature compensation
 Touch probes for measurement of milling and drilling tools
 Breakage detector in order to detect broken tools

These systems are designed for permanent installation in a machine’s work envelope. Thatway you seamlessly integrate tool measurement and status inspection in the production
process.

Three tasks, one vision system: the VT 122

 Detection of the tool status
 Tool measurement
 Optical inspection
 Wear measurement

The new VT 122 measuring camera with the VTC software from HEIDENHAIN combines
three roles in a single system, providing an all-in-one tool presetter, tool microscope andvisual inspector. Worn or damaged tools are therefore detected in a very quick and reliable
manner that can even be automated. There is no need to send them to a metrology lab.
Applications: Tool presetting and measurement
 Visual tool inspection before critical machining steps
 Documentation of tool status and wear values
 Contact-free breakage detection
 Panoramic images for inspecting the lateral cutting edges
 Inspection of flake faces and rake faces

3Your benefits: Increased productivity and reduced TCO
 Reproducible documentation of the tool condition
 Highly rugged design Compressed air efficiently cleans the workpiece and camera Automatic calibration and setup of the camera:

Separate TNC probing cycle for calibration

VTC computer software
The camera takes close-up images of each tooth as well as detailed panoramic images ofthe entire tool circumference. During inspection with the VTC computer software, thelighting angle can be varied for these panoramic images, enabling optimal illumination of all
cutting edges. This is ideal for measuring tool-flank wear. Tools can also be imaged whilelooking head-on at the tip. VTC can run automatically during unattended shifts (with cycles
for the TNC7 and TNC 640). Via an interface to the TNC’s tool table, the PC software caneven lock tools as needed.

The tactile TT touch probes let you measure your milling and drilling tools efficiently and reliably. Due to their rugged design and high degree of protection, these tool touch probes canbe installed directly within the machine tool’s work envelope. Tool measurement is possible
at any time: before machining, between machining steps, or after machining is done.
Applications: Cycle-controlled tool inspection
 Tool presetting Inspection of individual cutting edges

Your benefits: Fully automatable tool breakage inspection
 In-process tool inspection
 Simple installation and start-up
 Variable mounting with a wireless TT 460
 Automatic calibration after mounting and maintenance Rated break point protects the touch probe and spindle
 Sturdy and designed for a long life (over 50 million cycles) Wear detection
 Tool measurement
 Tactile inspection
 Repeatability: <1 µm

TD 110 tool breakage detector
The inductively operating TD 110 tool breakage detector inspects tools as they pass by,saving much time when looking for broken tools. Rotating tools moving at rapid traverse
can be measured. The TD 110 can be placed anywhere in a machine's work envelope. Tool
inspection can therefore take place at an ideal location, for example by integrating it in thetool exchange sequence. Thanks to the sensitive scanning technology, even very small tools
made of HSS steel or carbide can be inspected (starting with a diameter of at least 0.4 mm).
Applications: Contact-free tool breakage inspection
 Inspection routine upon tool changeYour benefits: Particularly efficient breakage inspection
 Inspection at rapid traverse
 Sturdy design for installation in the work envelope Compatible with all controls with a touch probe interface
 Cycles can be installed on the TNC remotely

 Tool breakage detection
 Inductive inspection
 Contact-free inspection
 Detection of complete breakage
