2.4.4. Manual feeding
Manual feeding: this system allows X axis or Z axis positive/negative motion at current manual
feeding speed in the manual mode, X axis and Z axis can’t move simultaneously. The actual manual
speeds in X axis direction and Z axis direction are adjusted with the manual ratio adjustment key in
the range 10%~150%. The manual speed of each level is the product of the fixed value set by the
system parameter and manual ratio, and the manual speed of every axis is set by the parameter
independently. When manual fast moving key is valid, manual speed uses the fast moving speed of
every axis, and manual ratio is invalid.
Manual feeding ratio isn’t saved after power off, and the initial ratio is 100% after electrified.
2.5. Tool compensation function (T instruction)
The system allows automatic tool change, and can control the automatic tool holder of position 4~8 to
change tools during the processing, achieving the part processing of multi-process and multi-tool.
The system also allows tool length compensation, which doesn’t need to consider the actual position
of the tool while programming, and only needs to get the position offset data of every tool (tool offset)
through tool setting operation before processing. Before processing with tool, execute tool length
compensation first, i.e. offset the system coordinates according to tool offset to make the motion track
of the tool tip consistent with the programming track. After tool is changed, the user only needs to
reset the tool and modify tool offset, and doesn’t need to modify processing program. If the
processing size has error due to tool abrasion, modify tool offset according to tool offset directly to
eliminate processing size error.

Tool offset No. (00-16, leading 0 can’t be omitted)
Target tool No. (00-08, leading 0 can’t be omitted)
Instruction function: automatic tool holder changes tool to target tool No., and executes tool
length compensation according to the tool offset corresponding to the tool offset
No. of the instruction. Tool offset No. may be same to or different from tool No.,
