SPC stands for Statistical Process Control. Cp and Cpk are statistical tools used to measure process capability.

• SPC is a method of monitoring and controlling a process to ensure it is operating within acceptable limits.

• Cp is a measure of how well the process is centered between the upper and lower specification limits.

• Cpk is a measure of how well the process is capable of producing within the specification limits.

• Cp an...read more

OEE can be calculated by multiplying Availability, Performance, and Quality percentages.

• Calculate Availability by dividing Operating Time by Planned Production Time.

• Calculate Performance by dividing Actual Production by Maximum Production.

• Calculate Quality by dividing Good Units by Total Units Produced.

• Multiply Availability, Performance, and Quality percentages to get OEE.

Major losses affecting OEE include availability, performance, and quality losses.

• Availability losses occur when equipment is not running due to breakdowns, changeovers, or lack of materials.

• Performance losses occur when equipment is running below its maximum speed or efficiency.

• Quality losses occur when defective products are produced and need to be scrapped or reworked.

• Other losses may include startup and shutdown los...read more
