 In time and motion study, the symbol 'X' represent

• Crossing
• Opposite directional movements
• Rejections
• None of the above

Which of the following is unaboidable delay?

• Waiting for raw material
• Non-availability of power

In tool signature the first figure represents

• Back rake angle
• End relief angle
• Side relief angle
• Side cutting edge angle

In tool signature the last figure represents

• Tool material
• Operation for which tool is made
• Nose radius
• Cutting speed

With high speed steel tools the back rake angle is usually zero while machining

• Aluminium
• Brass
• Cast iron
• Hand steel

In case of comented carbide tools the back rake angle is positive while machining

• Aluminium
• Brass
• Mild steel
• Carbon steel

Safety guards on machines should be

• Always in position
• Put in position of desired by the operator
• Used if they do not reduce the production
• Used sometimes

Bin cards are used in

• Machine loading
• Quality control
• Fixing targets
• Stores

The chart used to review the overall sequence of an operation by focusing either the movement of operators or materials is called

• SIMO chart
• NEMA chart
• Flow process chart
• Gaunt chart

CPM is a technique based on

• event
• event and activity
• neither event nor activity
• activity
