In India, the types of purchases practices include direct purchases, indirect purchases, and capital purchases.

• Direct purchases involve buying goods or services directly from the manufacturer or supplier.

• Indirect purchases refer to the procurement of goods or services that are not directly used in the production process, such as office supplies, maintenance services, or IT equipment.

• Capital purchases involve acquiring long-term assets like machinery, equipment, or vehicles.

We use high-quality stainless steel in our product for durability, corrosion resistance, and ease of maintenance.

• High-quality stainless steel chosen for durability

• Corrosion resistance is important for longevity

• Ease of maintenance for customer convenience

The Spindle orientation M code is used to control the orientation of the spindle on a machine tool.

• The M code for spindle orientation varies depending on the machine and control system being used.

• It is typically used to position the spindle at a specific angle or orientation for machining operations.

• The spindle orientation M code is often accompanied by additional parameters to specify the desired angle or orientation.

• Examples of spindle orientation M codes include M19, M155,...read more

1st angle projection is where the object is placed in the first quadrant, while 3rd angle projection is where the object is placed in the third quadrant.

• 1st angle projection is commonly used in Europe and Asia, while 3rd angle projection is commonly used in North America.

• In 1st angle projection, the object is imagined to be in the first quadrant and the plane of projection is between the observer and the object.

• In 3rd angle projection, the object is imagined to be in the thir...read more

Gears or transmission are mechanical components used to transfer power from one part of a machine to another.

• Gears are toothed wheels that mesh together to transmit motion and power.

• They can change the speed, torque, and direction of a power source.

• Types of gears include spur gears, helical gears, bevel gears, and worm gears.

• Transmissions are systems that use gears to control the power and speed of a vehicle.

• They can be manual, automatic, or continuously variable.

• Proper lubri...read more

Stress is the external force applied to an object, while strain is the resulting deformation or change in shape of the object.

• Stress is the force applied to an object per unit area, measured in units like Pascals or Newtons per square meter.

• Strain is the change in shape or size of an object in response to stress, measured as a ratio of the change to the original size.

• Example: A rubber band being stretched represents stress, while the elongation of the rubber band represents s...read more

Indirect purchase refers to the procurement of goods or services that are not directly used in the production process.

• Indirect purchases are typically made for support functions or overhead expenses.

• Examples of indirect purchases include office supplies, maintenance services, and IT equipment.

• These purchases are necessary for the smooth functioning of a business but do not directly contribute to the production of goods or services.

• Indirect purchasing often involves negotiatin...read more

Material details used in castings

• The material used depends on the type of casting process

• Common materials include iron, steel, aluminum, and copper alloys

• Sand casting typically uses silica sand and a binder

• Investment casting uses a ceramic shell and wax pattern

• Die casting uses a metal mold and high-pressure injection of molten metal

• Material properties such as strength, ductility, and corrosion resistance are important considerations

Forging materials include metals and alloys with high strength and ductility.

• Common forging materials include carbon steel, alloy steel, stainless steel, aluminum, and titanium.

• The choice of material depends on the desired properties of the final product, such as strength, durability, and corrosion resistance.

• Forging materials must have high ductility to withstand the intense pressure and deformation during the forging process.

• Some examples of forged products include automoti...read more

A simply supported beam is a beam supported at both ends with no moment resistance.

• Draw a straight horizontal line to represent the beam

• Add two vertical lines at each end to represent the supports

• Label the supports as 'A' and 'B'

• You can add a distributed load or point load for additional detail

Defects in casting and forging are common and can lead to product failure.

• Casting defects include porosity, shrinkage, and cold shuts.

• Forging defects include cracks, laps, and folds.

• Defects can be caused by improper design, material selection, or manufacturing processes.

• Quality control measures such as non-destructive testing can help detect defects before products are released.

• Examples of product failure due to defects include airplane crashes and bridge collapses.

Stress strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.

• Stress strain curve is a graphical representation of the relationship between stress and strain in a material.

• It typically consists of a linear elastic region, a yield point, plastic deformation, and ultimate failure.

• The slope of the curve in the elastic region is the material's Young's Modulus.

• The yield point indicates the onset of plastic deformation.

• Th...read more

Types of gears include spur, helical, bevel, worm, rack and pinion, and planetary gears.

• Spur gears have straight teeth and are the most common type.

• Helical gears have angled teeth for smoother operation.

• Bevel gears have cone-shaped teeth and are used to change the direction of rotation.

• Worm gears have a screw-like appearance and provide high gear reduction.

• Rack and pinion gears convert rotational motion into linear motion.

• Planetary gears consist of multiple gears working toge...read more

Sales is the process of selling products or services, while marketing is the process of promoting and creating awareness about those products or services.

• Sales involves direct interaction with customers to close deals, while marketing involves creating brand awareness and generating leads.

• Sales focuses on short-term goals, while marketing focuses on long-term goals.

• Sales is more transactional, while marketing is more relationship-oriented.

• Sales is a subset of marketing, as ma...read more
