Machining From Castings, Sketches and Raw Stock in Tracy: Andy’s Machine Shop

People arrive at a machine shop in different states of readiness. Some have a complete drawing with every dimension. Some have a rough sketch on paper. Some bring an old part and say, make me another one. A good shop works with all three, but what you bring changes the questions it will ask. Buyers in Tracy often wonder how much preparation is needed. Andy’s Machine Shop is listed here for CNC milling, CNC turning, prototyping, production machining, assembly, castings and consulting. This page explains what each starting point looks like.

Starting with CAD files

If you have a 3D model, send it in a common format along with a print that lists the material and tolerances. A model gives the shop the exact shape, and the print tells it what matters. This is the quickest path to an accurate quote.

Starting with a drawing

A dimensioned drawing is a good start, even if it is on paper. Check that every feature has a size, and that the material is stated. If something is missing, expect questions. Answering promptly helps keep the order moving.

Starting with a sketch

A hand sketch can work if it shows the shape and the key measurements. The shop may turn it into a model before machining. That time appears in the quote. A sketch with notes about how the part is used makes the job easier.

Starting with an existing part

Sometimes the best reference is the part itself. A machinist can measure it and make a copy or an improved version. If the original is worn, say where. Bringing mating parts is even better.

Raw stock versus castings

Parts can be machined from raw stock, such as bar or plate, or from a casting that already has the rough shape. Machining from raw stock removes more material and may take longer. A casting is closer to the final form, but it must be made first, and it needs machining only where accuracy is needed. Sometimes a modified existing part is the quickest route.

Parts of modest size

Many small shop jobs involve parts a person can lift. Brackets, fittings, spacers, shafts, plates and fixtures are typical. At this size, setup and programming can be a large share of the cost, so asking for more than one part at a time can lower the unit price.

Every industry and every shelf

Machined parts appear everywhere, from high-tech equipment to everyday hardware. A shop that serves many fields tends to be adaptable. Tell it what field you work in, so it can think about the standards that may apply.

Prototyping and consulting

If you are developing a product, a conversation before the order can help. A shop might suggest a simpler shape, a more available material or a different process. Treat that as a part of the service.
