1 Application report STAMA 331 Compact of the monitoring system Toolinspect 3 - button operation Machine: Spindle drive : Data transmission: CNC - control: Stama MC331 9,5KW Digital Siemens 840D This document is for information purposes only. Technical modifications reserved.

2 Advantages in connection with the tool- and process monitoring system series production., in at the development the simple operation and minimal imbeddings were in the centre in the NC programme. a small instruction of the using staff is sufficient for Toolinspect Simple operation via 3 functionkeys. Choose between 19 languages. the system becomes (shift, milling, drill, graters, threads etc., at different CNC engines with different process.) Toolinspect can be operated with the common CNC controls. (Siemens 840D/840Dsl/828Dsl, Bosch Rexroth, Fanuc, Indramat, Bosch, Heidenhain) process fluctuations are recognized automatically and the supervision limits adapt to the changes without intervention of the operator. automatic system and data saving on an external CF card. external module with mobile -- of one's own processor. Optional extension adaptive control of rough machining to reduce the processing time. automatic reconnaissance of tool change over tool magazine and therefore no operation necessary. torque and way information is selected from the CNC control. Higher processing speed can hereby be driven. a more exact supervision is guaranteed selection of processings in three single Sekmente by here: material touch (fluctuations) middle process (constant processing) finishing process (possible fluctuations) Further information: Monitoring straight after tool change. Process analysis with data interpretation for technologists and export function of the actual values and machine data to Excel. Robust flash memory Optional extension: storage of up to 250 different alarm messages for 96 hours. Page: 1

3 Monitoring system: The device is used to monitor tools on metal-cutting machines. The data, necessary for this task are normally transmitted to the device by a CNC control via a Profibus-DP interface. The monitoring strategy is automatically selected by the integrated software, according to the tool or machining process. The necessary parameters are determined and entered individually for one machine type by the machine tool manufacturer. No changes or adjustments are then necessary in the NC program or via the visualization interface. Pic. Siemens 840D / PCU50 Pic. GE Fanuc / 16i 32i The visualization on external Windows Computers (from Win98) gets connected via a TCP/IP or RS232 interface with the Toolinspect hardware. Alternatively the visualization can be displayed on an extra operating panel. Page: 2

4 Cycles: The tool monitor we activated for every tool explicitly and deactivated again. The following cycles are available: TI_PROG(1234) TI_ON TI_OFF TI_PROG: The programme number is submitted to Toolinspect with this cycle. Example: N120 TI_PROG(1234) This function must always stand at the beginning of a NC program. TI_ON: The tool monitor is started with this function. He will submit parameter "(1)" if the time axis shall be activated in Toolinspect (work on it at milling tools in several axes). This function is programmed in the NC program at every tool after the tool change. Example: N130 TI_ON (Way axis active) N230 TI_ON(1) (Time axis active) TI_OFF: With this function the tool monitor is turned off. This function is always programmed at the end of a processing before the next tool change. Example : N330 TI_OFF In case of any problems with one tool or one cut you can deactivate one cut with TI_OFF and reactivate the next cut with TI_ON. Tool: Toolinspect T-Nr. T- Number (840D) Name Missing tool recognized T13 T811 Milling T14 T112 Screw tap M6 T12 T110 T9 T804 Milling T6 T143 Drill 4,2 / 5,5mm T15 T814 Drill 3,5mm T2 T277 Milling T10 T815 T5 T805 Brush T16 T1060 Nozzle Page: 3

5 Notes: After the installation from the system was operated with work pieces. The System could find the tool monitor limits out for the cutting automatically. Function test: Torque differences between empty work and cutting show no evaluable the following tools. Therefore a missing tool cannot be recognized for certain here: T805 a brush T1060 a nozzle A groove is processed with the milling tool T804. A tool monitor would be conceivable here in future. The tool monitor algorithm in the Toolinspect software should be modified for this processing. MCU will work out a solution here within the next weeks. It is the tools T805 and T1060 a brush or nozzle these can be supervised only on collision. Graphic: This tool brings about blunt signals and is for certain wide awake cash T143 Page: 4

7 Operation and visualisation with a Windows - System : 1 Reset limits button This button resets the system for the active program (the program which is displayed in the interface under Prog. no.:) to the original values and relearn is carried out. Relearn button This button is used to carry out relearn. The program-specific data (increased limits) are not reset. The limits readjust to the actual values in the following machine cycles. Increase limits button If an incorrect message is generated by Toolinspect, the limit of the relevant fault message (switching threshold which generates a fault message) can be increased by pressing the F2 button. If this cut is reactivated in the next machine cycle, the increase of the limit is marked in yellow. Help button This button is used to call the Help function. Monitoring remains active. All histories of alarms are displayed as a sub-item ALARMS. Page: 6

8 Operation and visualisation with a Windows - System: 2 << Channel button This button is used to switch over (decrement) the active channel, e.g. from channel 2 to channel 1. Channel >> button This button is used to switch over (increment) the active channel, e.g. from channel 1 to channel 2. Wear button This button is used to visualise wear monitoring. This is an option. If the option is not activated, a demo screen appears here. End button This button ends the visualisation. Monitoring remains active. Displays In the left-hand section of the screen, displays show the increased and deactivated limits in yellow or orange. In the middle of this display, an alarm of the relevant limit is shown in red.

9 Summary: The operation is rather simple and in the CNC programme only insignificant customizations must be carried out. At type change or after the construction of new programmes or technology changes no customizations by the operator are required. The system adapts to different operation situations (wear, temperature changes etc.) automatically. MCU GmbH & Co.
