10+ Effica Automation Interview Questions and Answers

There are three main types of lathe operations: facing, turning, and boring.

• Facing: Removing material from the end of a workpiece to create a flat surface.

• Turning: Removing material from the outer diameter of a workpiece to create a cylindrical shape.

• Boring: Enlarging an existing hole in a workpiece.

First angle and third angle are two different methods of representing orthographic projections in engineering drawings.

• First angle projection is commonly used in Europe and Asia, where the object is placed in the first quadrant of the projection plane. The views are obtained by projecting the object onto the planes of projection.

• Third angle projection is commonly used in North America, where the object is placed in the third quadrant of the projection plane. The views are obt...read more

PPAP documentation serves the purpose of ensuring that suppliers meet quality standards and specifications for parts and materials.

• PPAP stands for Production Part Approval Process.

• It is a set of documents and records that demonstrate a supplier's ability to consistently produce parts that meet customer requirements.

• The purpose of PPAP is to ensure that suppliers have a robust quality management system in place and can provide evidence of their capability to meet quality stand...read more

Machining processes involve removing material from a workpiece to create the desired shape and size.

• Common machining processes include turning, milling, drilling, and grinding

• Turning involves rotating the workpiece while a cutting tool removes material

• Milling uses a rotating cutter to remove material from the workpiece

• Drilling creates holes in the workpiece using a rotating drill bit

• Grinding uses an abrasive wheel to remove material and create a smooth surface

• Other processes ...read more

Types of cutting include abrasive cutting, chipless cutting, and shear cutting.

• Abrasive cutting involves using abrasive particles to cut materials.

• Chipless cutting involves using tools to deform materials without creating chips.

• Shear cutting involves using shear forces to cut materials.

• Examples include laser cutting, waterjet cutting, and guillotine cutting.

Correction in mould after trial is a common practice to ensure quality and accuracy of the final product.

• After the trial, the mould is inspected for any defects or imperfections.

• If any issues are found, the mould is corrected by making necessary adjustments.

• This may involve modifying the design or making changes to the machining process.

• The corrected mould is then tested again to ensure that the changes have been effective.

• This process may be repeated multiple times until the...read more

Shift calculation of month and OEE formula

• Shift calculation involves determining the number of shifts in a month

• OEE formula is used to calculate Overall Equipment Effectiveness

• OEE = Availability x Performance x Quality

• Availability = Operating Time / Planned Production Time

• Performance = Actual Production Rate / Ideal Production Rate

• Quality = Good Units Produced / Total Units Produced
