Accessing the calculator
The built in calculator can be used for simple arithmetic, or other math 
functions. The calculator can be accessed at any time, during most 
operations.
The mathematical functions; +, -, x, and ÷, can be access at any time 
using the numerical key pad.  These functions are normally accessed 
while in a field of a dialogue during PGM mode.
Refer to Chapter 9 Geometry Calculator on page 210 for a complete 
description, and how to use the Geometry Calculator to perform  
complex geometry, and RPM calculations.
Using the calculator to insert data
The calculator can be used in the numeric field of dialogues.  
Example, Milling a circle pocket:  
The radius of a circle is required in the data input field, and the part 
drawing provides a diameter dimension.
The diameter dimension can be entered into the dialogue field.
Then press the Divide by key. The ( ÷ ) divide by 
symbol will appear in the field showing the calculation 
step. 
Then press the 2 key.  This will also appear in the field 
as part of the calculation steps.
Then press the ENTER key, and the result will be 
entered into the dialogue field.

4.1  Tool Table
Overview
When the MILLPWRG2 runs a program step that activates a tool, it 
only activates the diameter, and length values on that row of the Tool 
Table. The tool number, or tool type are not activated in dialogues that 
have these fields.
Tool Table values are automatically converted to their inch or 
millimeter equivalents when the MILLPWR
G2 mode is changed.  All 
typed values must match the current unit mode of the MILLPWRG2.
Define and store up to 99 tools on the tool table.  Type of data stored 
on the Tool Table is information specific to each tool.
Tool compensation required data
You usually program the coordinates of path contours as they are 
dimensioned on the work piece drawing. To allow the MILLPWRG2 to 
calculate the tool center path, e.g. the tool compensation, you must 
also enter the diameter of each tool you are using.
Tool data can be entered either directly in the part program or 
separately in the Tool Table. In the Tool Table, you can also enter 
additional data for the specific tool. The MILLPWR
G2 will consider all 
the data entered for the tool when running the part program.

4.1 Tool Table
Tool numbers / tool names
Each tool is identified by a number between 0 and 99. The tool name 
is its tool number.
The tool number 0 is automatically defined as the zero tool (empty 
spindle) with the length L=0 and the diameter D=0.
Sign for the length difference ΔL
If the tool is longer than the T1 tool: ΔL>0(+).
If the tool is shorter than the T1 tool: ΔL

Editing the tool table
When the tool table is open, a new tool can be added, or an existing 
tool can be edited by changing the existing information for that tool.
To enter a new tool, a blank numbered row will need to be selected.
Using the ARROW keys, highlight the next available blank row number.
Highlight the Diameter field, and using the numeric keypad, enter 
the tool diameter. 
Press the ENTER key. 
ARROW over to the next field and enter the tool Length if it is to be 
used.
Press the ENTER key.
ARROW over to the Type field and press the ENTER key.  The Type is 
only for informational purpose.
From the drop down menu, ARROW down to select the description of 
the tool that is being added (e.g. flat end mill).
Press the ENTER key.
Arrow to the next field and enter the plunge angle.  When ramping 
into a pocket, this is the angle at which the tool will enter the 
material.
Press the ENTER key.
Continue to add additional tools as necessary.
When all tools have been added, press the Exit soft key, or USE key 
to save changes to the tool table.
Press the Teach soft key.  The MILLPWRG2 calculates 
the tool length offset for the selected tool putting the 
data to the length column.
It is necessary to first select the unit of measurement 
before entering values into the tool table.
