Tool Load Monitoring Function (Option)

4.1

Introduction

This manual is about TC software Package. That is applied to our specification. Developed
package software function for user convenience features are as follows.
(1) Basic concept
TLM( Tool load monitoring) protects tool and tool holder from the further damage. If
TLM detect the abnormal load during the cutting process, machine will change
replacement tool or escape from cutting condition and stop by the level of abnormal
load. (SHOP TURN programming). In the normal operation, it sets workload range from
Min to Max for each Servo drive (Main spindle, X, Z, Y, X, M, Milling spindle, Sub
spindle) of each tool. If TLM detects a certain value of off-range, it will generate Cycle
alarm.
- If detection load is smaller(small tap, small drill), TLM cannot detect tool broken
situation.
- The value of the Minimum Current [A] and Maximum Current [A] for the current tool
save as internal variables during real cutting.

-. Red: Max/Min value of axis drive setting
-. Green: Max/min value of real cutting
-. If axis moved G01/G02/G03/G33/G331
/G332 cutting feedrate, detect current load.
-. Detection position can be set by screen.
-. Dimensions always is WCS (workpiece
coordinate system).
