Toggle-Rope Competition ofM R il C
Objective: To construct a self-contained mono-rail cars powered
by a
single motor
Mono-Rail Cars
single motor Winning car must keep the flag in its own
field.
Restrict yourself to the material given (to be posted). Project
description and details on the course webProject description and
details on the course web. Each group could design its own car.
Each group does not need to give a presentation but needs to
submit design in the interim reportsubmit design in the interim
report. Machining constraints:
Cutter 0.125 end mill- Rapid prototyping is also available
Suggested feed rate 8 in/min Suggested plung 8 in/minSuggested feed
rate 8 in/min, Suggested plung 8 in/min,
Suggested retract 8 in/min. 1000 rpm. Use only given boards Use
2 passes for safety reasons

23Fixed Automation
th f i ti i fi d b ththe sequence of processing operations is
fixed by the equipment configuration.

custom-engineered equipment high production rates relatively
inflexible in accommodating product variety

24Flexible AutomationC bl f d i i t f t ith i t ll ti l t f
Capable of producing a variety of parts with virtually no time lost
for changeovers from one part to the next. (minimal differences
between parts)

25Programmable Automation Production equipment is designed with
the capability to change the sequence
of operations to accommodate different product configurations
high investment in general purpose equipment lower production rates
than fixed automation flexibility to deal with variations and
changes in product configuration most suitable for batch
production

26Why CNC?
Machining operations: Generating -
geometry of work isgeometry of work is determined by feed
trajectory
Forming - shape of g ppart is created by the geometry of cutting
tool
Wh i iWhen is using a forming tool economical?

27Why CNC?
