  1. Generating Motion • Moving a part adds no value (except in packaging)‏ • Moving a tool adds no value unless work is done on part. • So, we want to avoid moving parts or tools any more than necessary

  2. Linear Motion • Linear translation is most common motion • Linear movement can be caused by: • Pneumatic or hydraulic cylinders • Rotary motion converted to linear • Vibratory systems • Electric solenoids • Linear electric motors • Piezoelectric actuators

  3. Pneumatic Systems • Pneumatic power very popular in industry • High force, economical linear motion • Non-flammable, compressible, storable medium • Compact, low heat production actuators • Pneumatics best suited to discrete motion (not proportional)‏

  4. Pneumatic Systems • Ideal Gas Law: PV=mRT • Boyle’s Law: P1V1 = P2V2

  5. Pneumatic System Layout

  6. Air Preparation

  7. Single-Acting Cylinder

  8. Single-Acting Cylinder

  9. Double-Acting Cylinder

  10. Pneumatic Cylinder Mounting • Off-axis loading must be prevented! • Pivoting mounts can eliminate axial loading: • Clevis mount • Trunnion mount • Universal joints • Shaft may rotate unless antirotation model is used
