8.11 Language commands for tool monitoring
8.11.1 Overview of tool monitoring
Functionality
This function is available for SINUMERIK 802D sl plus and 802D sl pro.
The tool monitoring is activated via machine data.
The following monitoring types are possible for the active cutting edge of the active tool:
S Monitoring of the tool life
S Monitoring of the workpiece count
The above-mentioned types of monitoring can be activated for one tool (T) simultaneously.
The control / data input for the tool monitoring is preferably done through the operation. In
addition, various functions can be programmed.
Monitoring counter
Monitoring counters are provided for each monitoring type.
The monitoring counters run from a set value > 0 towards zero. Once a monitoring counter
has reached the value <
0, the limit value is deemed to be reached. A corresponding alarm
message is issued.
System variable for type and condition of the monitoring
S $TC_TP8[t] ; Status of the tool with the number t:
Bit 0 =1: Tool is active
=0: Tool is not active
Bit 1 =1: Tool is enabled
=0: not enabled
Bit 2 =1: Tool is disabled
=0: not disabled
Bit 3 : reserved
Bit 4 =1: Warning limit reached
=0: not reached
S $TC_TP9[t] ; Type of the monitoring function for the tool with the number t:
= 0: No monitoring
= 1: (Tool) life-monitored tool
= 2: Quantity-monitored tool
These system variables can be read/written in the NC program.
