2 Broken tool detection
TRS1 non-contact broken tool detection system
This guide describes how to use the TRS1 non-contact broken tool detection system
software. The TRS1 is a laser non-contact system that provides high-speed/high accuracy
broken tool detection for solid tools only. As tools are moved into the laser beam, the
system detects reflection. Output signals are sent to the controller and the presence of the
tool can be established. The TRS1 system allows the following parameters to be
established:
z Detection of a broken tool.
NOTE: Solid tools – this means a tool where the cutting teeth do not protrude below the
centre point of the tool. Tools such as drills, taps, etc. are considered suitable tools.
Machine spindle speed checking
All broken tool detection takes place at a fixed spindle speed of 1000 rpm.
The active spindle speed is stored at the beginning of the broken tool macro. The broken tool
checking then takes place at 1000 rpm before resto ring the spin dle spee d back to its original
rpm.
Software memory requirements
Two Programs are supplied, if the broken tool check is to be called from a Mazatrol
program then O1001 will need to be loaded to the control. If the program is going to be
called from the ISO side the O1000 will require loading.
If the TRS1 is to be used in both Mazatrol and ISO then both programs can be loaded.
z O1000 (broken tool check ISO) 1.5 kb (3.75 metres) of memory.
z O1001 (broken tool check Mazatrol) 1.15 kb (2.875 metres) of memory.
Machine tool controllers supported
TRS1 system software is suitable for use on the following machine tool controllers.
M32,M-Plus,Fusion 640

Measurement values used in this guide
Throughout this guide, metric units of measurement, i.e. millimetres, are used in the
examples. The equivalent imperial measurements, i.e. inches, are shown in brackets.
Installing the software
Before installing the TRS1 software, read the guidelines contained in the readme file on
the CD.
Setting data in macro (O1000 or O1001)
Read the following variable descriptions then edit macro O1000 as described.
#14 = ‘X’ axis laser beam position. This defines the position at which broken tool
checking will take place in the X axis. (Machine positional values are
required).
Default: 0
NOTE: If the installation requires no X move to position the tool in the beam, then #14
requires no adjustment.
#15 = ‘Y’ axis laser beam position. This defines the position at which broken tool
checking will take place in the Y axis. (Machine positional values are
required).
Default: 0
NOTE: If the installation requires no Y move to position the tool in the beam, then #15
requires no adjustment.
#16 = ‘Z’ axis laser beam position. This defines the position at which broken tool
checking will take place in the Z axis. (Machine positional values are
required).
Default: 0

4 Broken tool detection
#17= Tool offset type.
1= Tool lengths stored in Mazatrol tool data.
2= Tool lengths stored in tool offsets (type A).
3= Tool lengths stored in ISO Tool data.
4= Tool lengths stored in tool offsets (type B).
#18= Skip code
This setting must be checked. With the incorrect setting the machine will
not detect a broken tool.
The machine should be connected so that G31.2 is used for the TRS1
move. If the machine is wired differently, change #18 to suit the skip
command being used. The default value is #18= 31.2.
