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– One metal machining batch factor: 95% of a
parts time is spent moving or waiting, 5% of time is on tool, of which only 30% is spent cutting.

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

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)

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

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
