MAP full form

 What is the full form of MAP?

Answer:

• Manifold Absolute Pressure

What does MAP mean?

MAP is a sensor that is used by the powertrain control module for engine load input. The PCM uses this input. It is also calculated the correct amount of fuel to inject into the cylinders. The MAP sensor tests the absolute pressure inside the engine's intake manifold.

BCD full form

 What is the full form of BCD?

Answer:

• Bolt Circle Diameter

What does BCD mean?

The diameter of the circle that passes through the middle of all of your chainring's bolts is known as BCD. This dimension is generally measured in millimetres on bicycle chainrings. When choosing a new chainring for your bike, knowing the BCD of your crankset is important.

Difference between Open-Die and Closed-Die Forging

What is Closed die forging?

The closed die forging is a metal forming process that compresses a piece of metal under high pressure to fill an enclosed die impression. For some special shapes, the second forging operation is required to reach the final shapes and dimensions.

What is Open die forging?

Open die forging is the process of striking a hammer to deform a piece of metal, typically placed on a stationary anvil. Another approach is to use compression to press the metal between the simple dies.

Difference between the open die and closed die forging:

• Open die forging is the workpiece is compressed between the two flat dies, while the closed die forging the workpiece is compressed between the two impressed dies.
• Open die forging the cost of dies is low, while the closed die forging the cost of dies is high.
• The process is simple in Open die forging, while the closed die forging process is complex.
• Open die forging machining of components is required, while the closed die forging, machining of the component are not required.
• Open die forging there is poor utilization of the material, while the closed die forging there is a better utilization of the materials.
• Open dies forging the dimensional accuracy of the obtained products is not good, while the closed die forging the dimensional accuracy of the obtained products is good.
• Open die forging is used for low-quality production, while closed die forging is used for high-quality production.
• Open die forging is suitable only for the production of the simple type of components, while closed die forging is suitable for the production of simple and complex components.

Difference Between Single Point and Multi Point Cutting Tool

The main key comparison between the single and multi-point cutting tool is the single point cutting tool contains only one main cutting edge while the multipoint cutting tool contains more than one cutting edge. So here this article gives the main key difference between single point and multi-point cutting tools to better understand this topic.

Difference between single point and multipoint cutting tool:

• Single-point cutting tools contain only one main cutting edge in the cutter body, while multi-point cutting tools contain more than one edge in the cutter body.
• Single point cutting tools is only one main cutting edge that continuously remains in contact with the workpiece, while the Multipoint cutting tool more than one cutting edge simultaneously engages in materials removal action in a pass.
• Single-point cutting tools are a chip load per tooth is usually high, while due to the presence of multiple cutting edges, effective chip load per tooth reduces.
• Design and fabrication of single-point cutting tools are easier, while the  Design and fabrication of multi-point cutting tools are quite difficult.
• Single-point cutting tools  example of turning tool, shopping tool, planning tool, slotting tool, boring tool, fly milling cutter, etc while the multi-point cutting tool example of milling cutter, hobs, broach, grinding wheels, reamer, knurling tools, etc
• Single-point cutting tools can be made from grinding machines, while the multipoint cutting tool can not manufacture from only grinder machines. 
• Single-point cutting tools the wear rate is high, while the tool wear rate is low in multi-point cutting tools.
• Single-point cutting tools have a low material removal rate, while the multi-point cutting tools good or more material removal compared a Single-point cutting tools.
• The tool life of Single-point cutting tools is shorter comparatively multi-point cutting tools. 
• In term of accuracy, this is one provides a good surface finish in the single-point cutting tool, while the multi-point cutting tool provide grater surface finish.
