Job description
Add a 12.7 mm (1/2 inch) Dia Drill to the tool library
Tool Data

- Drilling length: 50 mm
- Predrilling: not needed
- Type: Harvey Tools, 15332-C1

Open the data base
Open GSimple
Select Tools/Drills from the main menu
and press the New button

Name and geometry
Each tool must have a unique name in GSimple. You can choose any name you like. Blanks are
allowed in the name. Do not use underscores, since they will be converted into blanks! (Actually blanks are
internally converted into underscores and converted back into spaces at view time). Names are restricted to 39
characters.
Try to use meaningfull names, otherwise you will get lost.
We will name our drill DHSS1/2" (Acronym for Drill HSS 1/2 inch)
Fill in the requested data (diameter 12.7 mm, legth 50 mm, predriling diameter 0 mm) and press Enter.

Milling parameters
Milling parameters (tool speed, cuting depth and feed rates) are material dependent.
The tool manufacturers supply data, formulas and software tools to calculate them.
Materials are normally grouped together in Groups and Subgroups. Generally a tool is suitable for some
of these material-groups and unsuitable for others.
The tool-data-base is able to store a set of milling parameters for every material group and subgroup. GSimple
will look for the appropriate set (the block material is defined with the Setup/Block menu selection) whenever you
attach a new tool on the tool holder. If no milling parameters set is found in the data base for the block material
the tool will be market as UNSUITABLE.
There are only two milling parameters assosiated with a drill: speed and feed rate.
For material group 1.3(Plain carbon steel) our driil needs 540 RPM and a feed rate of
160 mm/min.
Select the new drill from the list and press the Mat.Data button.
Press the Add button
Select 1.3 Plain Carbon Steel, supply our data
and Press the OK button.

Ready!
Now we are ready to use our new tool with materials such as CK45 belonging to the 1.3 Group.
You can follow the same procedure to add milling parameters for other material groups or/and define
other tools.
