What are Machining Tolerances?   Machining tolerances refer to the allowable variation in dimensions, shape, and position of a machined part from the intended design specifications. These tolerances are essential because it is nearly impossible to manufacture parts with absolute perfection. Tolerances are specified to ensure that the machined parts fit together, function properly, and meet the required performance standards. They are expressed as a range of acceptable values within which the dimensions and characteristics of the part must fall.   When it comes to milling tolerances and lathe tolerances, precision is key in achieving accurate and flawless results. Understanding the CNC machining tolerance chart and adhering to tight tolerance machining practices are vital for ensuring high-quality outcomes. Tolerance in machine design, along with compliance with CNC tolerance standards, ensures the proper fit and functionality of machined parts. High tolerance machining requir...

BASIC PRINCIPLES Injection moulding is a formative manufacturing technology, i.e. material is formed from an amorphous shape into a fixed shape defined by a mould tool. Almost every plastic part created today is by injection moulding as it allows identical parts to be created in huge numbers, in a short space of time, and at very low cost per part.   The process works as follows:   1. A mould cavity defines the shape of the part. 2. Material (melted plastic) is injected under pressure into the cavity. 3. When the plastic cools it solidifies to take the form defined by the mould. 4. The part is ejected, and the process repeats from step 2.   Part Creation Whilst the part cost is low, injection moulding has high set up costs, mostly from the cost to make the tools (using CNC) Mould tools range from a few hundred GBP to over 100,000 GBP depending on complexity. The materials used for the tools varies depending on how many parts are to be made and the accuracy required. All ...
