  7. 7. 7 • Similar operations: • They differ in the kinematics of the process. • Both use a single point cutting tool moved linearly relative to the workpiece. • A straight, flat surface is created in both operations. • Low cutting speeds due to start-and-stop motion. • Typical tooling: single point high speed steel (HSS) tools.

  8. 8. 8 SHAPING AND PLANING by Endika Gandarias Components of a shaper. Components of a slotter machine. • Tool has reciprocating motion. • Workpiece is clamped on the table which is stationary. (HORIZONTAL) SHAPING MACHINE VERTICAL SHAPING MACHINE OR SLOTTER MACHINE • Identical machine to a horizontal shaping machine but inclined 90º. • It allows a higher cutting power as the workpiece is better hold on the working table. Shaping VIDEO VIDEOVIDEO

  11. 11. 11 • It is a machining process that uses a multiple-tooth cutting tool, called broach, moved linearly relative to the workpiece. Each tooth is successively higher than the previous tooth. • The material is removed in one stroke (pulling or pushing) (main difference in comparison with shaping and planing). • Most broaches are made of HSS, although carbide inserts (brazed or mechanically attached) also exist. • It works best on soft materials: aluminium, bronze, brass, wood, plastics, composites, graphite,…  Dimensional tolerance ~ IT6 – IT8  Surface finish (Ra) ~ 6,3 – 25 μm Advantages: • Suitable for mass production. • Cutting time is quick. • Variety of work shapes possible. Disadvantages: • Owing to complicated and often custom-shaped geometry, tooling is expensive. • Valid only for light cuts. • Only through hole and surfaces can be machined. BROACHING by Endika Gandarias VIDEO
  12. 12. 12 BROACHING Parts made by surface broaching Surface broaching machine Surface broaching by Endika Gandarias • It is used to cut flat surfaces. • The tool is a simple flat bar with multiple rows of cutting teeth. • Surfaces may be flat, concave, convex, serrated or cam-shaped. VIDEOVIDEOVIDEO
  13. 13. 13 • It is used for enlarging long holes. • A starting hole must be predrilled in the part to insert the broach at the beginning of the stroke. BROACHING by Endika Gandarias Typical parts made by internal broaching Internal broaching machine Internal broaching VIDEOVIDEOVIDEOVIDEO

  15. 15. 15 SAWING by Endika Gandarias • Sawing consists in cutting a narrow slit in a workpiece using a tool consisting of a series of narrowly spaced teeth. • The tool is called a saw blade and the teeth are typically made of carbon steel, HSS, carbide or diamond. • Typical functions: • Separate a workpart into two pieces. • Cut off unwanted portions of part . Teeth are deviated in order to reduce friction between saw blade and part.
