The process of new tool making on CNC milling machine involves several steps.

• Designing the tool using CAD software

• Selecting the appropriate material for the tool

• Creating a toolpath using CAM software

• Setting up the CNC milling machine

• Machining the tool using the CNC milling machine

• Inspecting and testing the tool for accuracy and quality

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.

Force is a push or pull on an object, pressure is the force applied per unit area, and stress is the force applied to a material per unit area.

• Force is measured in Newtons (N)

• Pressure is measured in Pascals (Pa)

• Stress is measured in Pascals (Pa)

• Force can cause pressure and stress on an object or material

• Pressure and stress can cause deformation or damage to an object or material

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

There are several types of moulds used in injection moulding, including two-plate, three-plate, hot runner, and cold runner moulds.

• Two-plate moulds have a stationary half and a moving half that opens and closes to release the part.

• Three-plate moulds have an additional plate that separates the runner and gate from the part.

• Hot runner moulds use a heated manifold to keep the plastic molten as it flows into the mould cavity.

• Cold runner moulds have a separate runner system that i...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

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

Vernier caliper is a measuring tool used to measure the dimensions of an object with high accuracy.

• Clean the jaws and ensure they are parallel

• Close the jaws and check if the zero on the vernier scale aligns with the zero on the main scale

• Open the jaws and place the object between them

• Read the main scale value closest to the object's edge

• Read the vernier scale value that aligns with the main scale value

• Add the main scale and vernier scale values to get the final measurement

An engine is a machine that converts fuel into mechanical energy to power vehicles or machinery.

• Engines come in various types such as gasoline, diesel, electric, and hybrid.

• They are used in cars, trucks, airplanes, boats, and generators.

• Engines work by igniting fuel and air mixture to create a controlled explosion that moves pistons and generates power.

• Regular maintenance is required to keep engines running efficiently and prevent breakdowns.

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

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.

The zeroth law of thermodynamics states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.

• The zeroth law is the basis for temperature measurement and the concept of thermal equilibrium.

• It establishes the transitive property of thermal equilibrium.

• It allows us to define a temperature scale and compare temperatures.

• For example, if a cup of coffee and a thermometer are both in thermal equilibrium with a third...read more

PDI stands for Pre-Delivery Inspection.

• PDI is a process of inspecting a product before it is delivered to the customer.

• It is commonly used in the automotive industry to ensure that vehicles are in good condition before they are sold.

• During a PDI, technicians check various components of the product, such as brakes, tires, and electronics, to ensure that they are functioning properly.

• PDI is important to ensure customer satisfaction and reduce the risk of product returns or comp...read more
