CNH ( Case New Holland) Product Manager Interview Questions and Answers

Grinding is a process of removing material from a workpiece using an abrasive wheel. Multi-point cutting tools are tools with multiple cutting edges.

• Grinding is used to achieve high precision and surface finish on workpieces.

• Multi-point cutting tools are commonly used in machining operations such as milling, drilling, and turning.

• Examples of multi-point cutting tools include end mills, drills, and taps.

• The number of cu...read more

5S, Kaizen, and 7QC tools are all methodologies used in lean manufacturing to improve efficiency and quality.

• 5S is a workplace organization method that involves sorting, simplifying, sweeping, standardizing, and sustaining.

• Kaizen is a continuous improvement process that involves identifying and eliminating waste and inefficiencies.

• 7QC tools are a set of quality control tools used to identify and solve problems, includi...read more

Grinding defects are common in manufacturing processes and can affect the quality of the final product.

• Cracks or fractures in the material being ground

• Uneven surface finish

• Burn marks or discoloration

• Chatter marks or vibration

• Incorrect wheel dressing or selection

• Improper machine alignment or setup

• Inadequate coolant or lubrication

• Excessive wheel wear or loading

• Incorrect feed rate or grinding pressure

Plunge grinding and through feed grinding are two types of grinding processes used in manufacturing.

• Plunge grinding involves grinding a part by plunging it into the grinding wheel, while through feed grinding involves feeding the part through the grinding wheel continuously.

• Plunge grinding is typically used for parts that require a tight tolerance and a smooth surface finish, while through feed grinding is used for hig...read more

Grinding defects are common in manufacturing processes and can include chatter marks, burn marks, and surface cracks.

• Chatter marks are caused by vibration during grinding and appear as a series of regular marks on the workpiece.

• Burn marks are caused by excessive heat during grinding and appear as discolored areas on the workpiece.

• Surface cracks can be caused by a variety of factors, including improper grinding techniqu...read more

Plunge grinding and through feed grinding are two types of grinding processes used in manufacturing.

• Plunge grinding involves grinding a part by plunging it into the grinding wheel, creating a flat or tapered surface.

• Through feed grinding involves feeding the part through the grinding wheels, creating a straight and smooth surface.

• Plunge grinding is typically used for parts with complex shapes or contours, while through...read more
