Macromotion & Micromotion studies.

Key difference between Macromotion and Micromotion studies are as under :

Motion studies are performed to eliminate waste. Before any improvement in quality or quantity of output, any study of operations time, any scheduling of work or balancing of workload or any calculation of standard time, a study of the current and proposed method is required.

Studies of overall factory flow or process, called macromotion studies, and then additional studies of detail or operations, called micromotion studies, should be completed for a project.

Difference between Machine Time and Machine cycle time

The difference between Machine Time and Machine cycle time with example are as under:

Machine time:    

The time that machine is working on a product. Machine time is the time that machine is working on a product.

Machine Cycle Time:

 Machine cycle time is the average time of completed units coming out of the  machine.

Example :

In 6 working hours, machine is producing 6 product then cycle machine cycle time is 1 Hour.  And machine time is 6 hours.

Machine Cycle time :    Total machine cycle time / Units produced

Key Difference between Time & Motion

The key difference between Time and Motion are as under:

A: Motion study is for cost reduction, and time study is for cost control.

B: Motion study is the creative activity of motion and time study.

C: Motion study is design, while time study is measurement.
