Study Notes
Layout Work
- Layout work involves marking lines, circles, and arcs on metal surfaces based on a working drawing.
- Essential for showing the location and amount of metal to be removed during machining.
Layout Tools
- Various skilled metalworkers (e.g., die-makers, machinists) use layout tools for precision tasks.
- Tools include outside and inside calipers, angle plates, V-blocks, micrometers, and the combination set.
Outside Calipers
- Composed of two legs bent inward, used to measure outside diameters of round objects.
- Measurement taken at the widest opening between the legs using a layout rule.
Inside Calipers
- Two-legged steel instrument with legs bent outward, designed to measure hole diameters or spaces between objects.
- Useful for assessing accuracy of gear teeth and measuring form cutters or threading tools.
Vernier Height Gage
- Offers precision positioning of scribers with an accuracy of one-thousandth of an inch, primarily for layout tasks.
Bevel Protractor
- A precision instrument for measuring and laying out angles, divided into degrees for accuracy.
Angle Plate
- Constructed with two surfaces at a precise right angle (90°), often used to clamp workpieces during machining.
Parallel Clamp
- Also known as toolmaker’s clamp, utilized to hold parts together or to secure work against an angle plate.
V-Blocks
- Steel blocks with V-shaped grooves, typically used in matched pairs to hold round workpieces securely at right angles.
Micrometers
- Referred to as "mikes," they are instruments for making very fine measurements, essential for precision engineering.
Combination Set
- Includes a square or combination head, center head, bevel protractor, spirit level, and steel rule, widely used in layout work.
Punches
- Prick punch has a sharp point for marking precise locations on materials.
- Center punch, larger than prick punch, is used to create larger marks for drilling.
Machinist’s Hammer
- Features a ball-peen head, useful for shaping metal and delivering precise strikes.
Hacksaw
- Essential tool for cutting unhardened metals; consists of a frame, handle, prongs, tightening screw, wing nut, and a blade.
Hacksaw Blades
- Made from thin, high-grade hardened steel, with flexible options available for enhanced performance.
