Ch. 10 Flashcards
Standard data
a catlog of time standards developed from a database of collected standards over years of time studies
Advantages of SD
Is shorter than PTs. more accurate. can be set before production starts
most common SD formula
linear slope
Constant cyle times
mechanical punch press, time 10 actions, takes average
Feed rate what is it and formula
like welding. measures the distance traveled per revolution turning. inches per revolution.
Length of cut/ number of revolutions required.
basis of machine run time
speeds and feeds
Time standards consits of
Machine time and load/unload time.
speed measured in
distance traveled per minute.
Number of revolutions formula
lenght of cut/feed rate
Balanchign techique is used for
Equalizign the workload between operators, work stations. identify the bottleneck operation. Establishing speed of assembly time. Determine number of work stations. determine labor costs.
R value
the rate at which a part must be produced in order to meet customer demand. b
production rate with cycle time
conversions rate for time x however many lines or operators / Cycle time
machines required for fabrication operations
you add up all the partial machines, round up, and purchase that many.
Lead time
the time it takes for a product to made from start of production to the assembly.
purpose of assembly line balancing
same as the balancing technique but in addition helps with plant layout and reduces production costs. most important is to make sure that two operators are given the same amount of work for each value.
