- Marking out
Marking out or layout is the process of transferring a design or pattern to a workpiece, as the first step in the manufacturing process. It is performed in many industries or hobbies although in the repetition industries the machine's initial setup is designed to remove the need to mark out every individual piece.
Marking out consists of transferring the dimensions from the plan to the workpiece in preparation for the next step, machining or manufacture.
Typical tools include:
- Surface plate or marking out table — provides a true surface from which to work
- Angle plates — assist in holding the workpiece perpendicular to the table
- Scriber — is the equivalent of a pen or pencil. It literally scratches the metal surface leaving behind a fine, bright line
- Height gauge or scribing block — allows lines to be scribed at a preset distance, from the tables surface
- Surface gage — an ungraduated comparison measuring tool that performs much the same function as the vernier height gage. It is often used in conjunction with a dial indicator and a precision height gage.
- Marking blue — to provide a usable writing surface by covering any existing scratches and providing a contrasting background
- Profile gauge
- Protractor — to assist in the transfer of angular measurements
- Combination square — an alternative tool for transferring angular measurements
- Square — to transfer 90° angles to the workpiece
- Punches — either prick or center punch to create permanent marks or dimples for drill bits to start in
- Automatic center punch — a spring-loaded punch that creates prick punch marks without the need for a ball peen hammer
- Ball peen hammer — used in conjunction with the punches to provide the striking blow needed
- Dividers or measuring compass — for creating circles or arcs
The "chalk" is actually a small pre-cut block of talc (soapstone). These talc blocks can be sharpened to a stronger point than the softer blackboard chalk. The color of the chalk provides good contrast against the dark color of the hot rolled steel that is generally used.
