5.2.2 Tool Setting
Tool setting enables the CNC to apply the corrections necessary during movements.
The input tool dimensions are stored in the tool dimension table before being used in a part programme.
Tool dimensions can be input or loaded via:
- the keyboard,
- a peripheral.
The tool dimension table remains stored in the memory when the CNC is switched off.
REMARK The tool offsets can be modified by a part or PLC programme. The user must bear
this possibility in mind and re-enter the tool dimensions if required.
For each tool, three dimensions are defined (tool radius, tool length and corner radius: see 1.2.5 and 4.4) associated
with corrections D..
The corrections are not automatically allocated to a specific tool. The part programme associates a correction to a tool.
Several corrections can be successively associated to the same tool in a programme (during roughing and finishing
phases for example).
5.2.2.1 Semi-Automatic Tool Dimension Entry
During the semi-automatic tool dimension entry procedure, the CNC measures the tool dimensions against a reference
part.
These measurements are made when the tool is in contact with the reference part, defined using programme
dimensions.
Requirements
Homing completed on all axes (See 5.1.2).
DAT1 and DAT2 shift values entered (See 5.2.1).
Tool and reference part in place.
No mode being executed. If a mode is being executed, selection of this mode is only taken into account after an
interruptible block (mode substitution is not possible during a machining cycle).
Actions
Select one of the current position pages (See 4.2) or "TOOL OFFSETS"
(See 4.4).
Select the 2nd page of the Mode softkeys. ☞
