Specifying the Offset (1) Tool Offset by Tool Number If a “tool offset by tool number” option is added to the NC unit for the SEICOS-Σ, tool offset can be applied by a spindle tool number without taking offset data “H” and “D” into account, even if the spare tools are used.

Page 116: Cutting Monitoring Unit
19. Cutting Monitoring Unit 19-1 Outline The cutting monitoring unit monitors the cutting loads of the spindle and feed axes of the NC machine tool to prevent abnormal cutting and manufacturing of defective products. You can set monitoring data and monitoring functions for each tool to ensure detailed monitoring. The tool life management function is required because this unit is interlocked with it.
Page 117: Monitoring Functions
Selecting the Monitoring Function The monitoring functions for the main monitoring axis include overload detection, no-load detection, wear detection, adaptive control, and idle cutting time reduction, and those for the sub-monitoring axes include overload detection and wear detection. Select a desired function for each tool in the SET LOAD screen. 19-3 Monitoring Functions Overload Detection When a cutting load keeps exceeding an overload detection value for an overload judgment...
Page 118 Wear Detection When a cutting load reaches a state of wear load, that tool’s status is regarded “worn out.” Machining continues even if wear is detected, but that tool will be treated in the same manner as an out-of-life tool in a tool command in next machining. Since wear detection and adaptive control cannot be enabled simultaneously, disable adaptive control when you enable wear detection.
Page 119 Adaptive Control (Feed Rate Override Control) When a cutting load exceeds a no-load value into a cutting state, a feed rate override is controlled so that the cutting load will stay between an upper-limit adaptive value and lower- limit adaptive value. When the cutting load is still exceeding the upper-limit adaptive value for 2 seconds even if the override is minimized, an overload is detected, judging it a cutting error.
Page 120: Cutting Monitoring Program
19-4 Cutting Monitoring Program Cutting Monitoring Special M-code (1) Stopping/Resetting the Tool Life Management Function and Cutting Monitoring Function (M54/M53) Since a cutting load does not take place up to an actual machining start point in remachining from halfway, M54 is executed to disable the tool life management function and cutting monitoring function when cutting monitoring makes erroneous detection.

Page 123: Data Setting
19-5 Data Setting Selecting the Main Monitoring Axis In the SET LOAD screen, select the spindle, X-axis, Y-axis, or Z-axis as the main monitoring axis for each tool. When machining is done with this tool, determine on which one of the spindle motor, X-axis, Y-axis, and Z-axis a change of the cutting load is reflected, and set that axis as the main monitoring axis.
Page 124 [3] Setting the data by downloading Download the monitoring data from the NC program. (2) Automatic Setting Set the CUTTING MONITOR mode selector switch on the operation panel to AUTOMATIC DATA SET and perform teach cutting. The load reference value for the tool used for machining is calculated from the cutting data for the monitoring section and set.
Page 125: Cutting Monitoring Operation
Caution Every time the S-data is altered while the spindle is rotating , a cancellation time is activated. For the feed axes, the cancellation time is activated when cutting starts, but it is not between continuous cutting feed block. When the machine is operated in the SINGLE BLOCK mode, an axis is started at machine start time, and therefore, the cancellation time is activated every time.
