Ms. Barbara asked:


The Cad Cam machinery is based on CAD and CAM, the short of Computer Aided Design and Computer Aided Manufacturing respectively. As the term means, it simply means that the computer remote machines that can be used for the designing and the controlling of manufacturing processes purposes. The CAD and CAM machinery has its own value, it is so heavy and well equipped that it is used for the engineering and architectural purposes for drawing and sketching a really form of image making it more compatible for the technical usage. This can be explained easily that once the design is made by the CAD component, the design itself will control the machines involved in constructing that part, on the format.

Making it simple this can be explained in portions, let us first discus what does the CAD means and what machines do with CAD, as it is the short of computer aided designing, it directly signals that those machines are helpful in designing aspects, for the professionals, the engineers and for the architectural purposes. These machines are composed of special type of software and often hardware that includes the main geometry-authoring tool within the PLM process. As the CAD is the main type, according to its utility it has some different titles as well like the CADD and CAID, which defines as the computer aided designing and drafting, as the CAD is often termed as the drafting tool as well, and the computer aided industrial design and also the CAAD which means the computer aided architectural designs, these all titles tend to be similar but minor differences in the work manner have given it new names.

The new packages of CAD include the 2D vector based drafting system and the 3D parametric surface and solid design modelers. The CAD is a very useful tool for which it means a lot, it is not just a designing tool but it is high full-bodied designing tool. It is the power of computer designing sources that is merged with the heavy machinery to make it more compatible for the advanced functioning in the thermal processes, fluid flow analysis, stress analysis and shear analysis. The meaning of advanced designing is fulfilled with the use of CAD tool. It is simple to use and is highly effective, thus saving time and profiting the person who owe it. It is drastic software that is used in many purposes of work fields where time is less like CAD and CAM is used for the food processing as well to secure the speed of the production line. When it comes to the CAM, it simply means that it is helpful tools regarding manufacturing processes in definite time. It the tool that is aided by the computer in the robotic form so as to make the manufacturing purpose more enhanced. The CAM is used to make the procedure more easy and quick to make the yield in less time and less complex method.

The use of CAD and CAM together is very authentic and together they are used in different working areas to make the designing and manufacturing processes highly well suited. The CNC program is created with the CAM tool, the combination of CAD and CAM tools create a CNC program, the CAM usually comes wit the machine called lathe or chisel, the two if comes together costs very expensive that is more than $1 million. The two together offers great advantages because its accurate and focused functioning on the major and minor objects for correction, realigning and adjusting geometric positioning and aligning metric systems within it.

The CAD CAM machinery is used worldwide in schools and many organizations that create, invent or manufacture new products.

Antony G asked:


I am considering using a CNC beam saw to cut some MDF. I need to know if this type of machine would leave any saw marks on the cut surfaces of the material.

Basically, I need to find a way of cutting a large sheet of MDF (30mm thinkness) into 12mm strips. But finding a way to do this without leaving tool marks of the material. I’ve considered abrasive waterjet and a CNC router but now someone has suggested that a CNC beam saw might be the answer.

But it is very important that the material is cut very clean with no machining marks at all. Would a beam saw be ideal?
Re: Answer given by mega H.

Because of the way I want to use the material cutting 30mm strips from 12mm thickness mdf would not be possible. Also, I would need the cut surface of the MDF totally free of machining marks so that the grain of the MDF is extremely crisp and clear. I have tried sanding the MDF and that destroys the grain. If a drum sander was used would the finish be as clear and crisp as if the material was cut using say a router or even a abrasive waterjet?

“At this time the vendor will view the given information, usually comprised of dimensions of part and type of material needed as well as temper and strengths of the application needs for the part. There are also instances where some type of exterior or interior plating may be needed; this too is taken into consideration at the time of quoting.

These are some of the necessary tools needed to properly quote the machined part for production in the machine shop. Other areas of information include number of pieces required and lead time for production. At this time a quote for manufacture will be offered to the customer with a valid lead time and price for production as asked for in their original RFQ (request for quote). The buyer will at this time compare to other possible quotes and choose from them the best one that fits his/her criteria.

A Purchase Order is then received for the part quoted from the customer to the awarded vendor. The information on the purchase order will provide the vendor with part number, quantity ordered and delivery date needed by along with the price quoted by vendor. Some customers will even go a step further and put the vendors quote number on the purchase order for confirmation purposes. The vendor will now compare the purchase order to the quote offered and make sure that all information meets the quoted details and either accept or decline the P.O. This process is the contract review phase.

The challenge now is to determine the most efficient method to manufacture the parts per the print specifications i.e. CNC machining, fabricating, stretch forming, hydro forming. A procurement specialist for the awarded vendor will now begin the task of sending out their own RFQ’s for material and any outside processing that will need to be done, as well as creating a job router for the part for traceability purposes. Aerospace machine shops should hold quality requirements per the AS9100 standard, which requires material tractability throughout every step of the machining process. This job router has all the information from the purchase order on it and will travel with the material from beginning to end. Once the material has been ordered and received it will usually go through a saw process determined by a machine programmer. Now the cut material will go to a designated machine for shaping, either by manual means or CNC (automatic). After the part has completed its time at the machine, it will go through a vigorous inspection process to assure the customer a part that complies with the information provided. Now the part will go to any plating or other outside processing and return for shipping to customer with the satisfaction of knowing that all needs have been met. 100% first article inspection reports are and all other documentation per AS9100 are sent with parts to the customer for final review.

Quality systems are a paramount function of any and all manufacturing of parts. Quality systems such as AS9100 and ISO9001 direct a company to uphold some of the highest quality standards in the manufacturing industry. A company’s quality statement and quality policy should be know and respected by all employees in the organization. Quality starts form the top levels of management and flows downward to the shop floor. “

differences between a cnc milling machine and a cnc machine center

Ivan Irons asked:


Keeping your shop clean

My first inclination is to say that it can’t be done in your home shop. My experience in my home shop has been that machining creates dirt. I use the term dirt very loosely. Dirt in many forms like plasma dust, machining chips, and cutting fluid spray. All of these forms of dirt are very invasive and get into everything. You constantly have to be cleaning just to keep up.

In my home shop experience, I treat every one of my machines differently. My CNC plasma cutter is the dirtiest by far. I built a special room for it to try to contain the plasma dust it creates. My milling machine is in my main working area. I usually just have to clean around it from time to time. My CNC Wood Router is located in my woodworking shop. It creates a lot of wood chips and wood dust, which all my other woodworking machines do as well.

Factories invest in thousands of dollars in extra machines to keep things clean. These machines purpose is to reduce the amount of dirt in the shop. Some of these machines clean the air and some of these machines take care of the physical chips leftover from machining.

Here are some examples:

Automated Chip Augers - Chip augers are generally in the belly of machines. As chips fall down the augers move them over to a collection area. These chips can then be shipped out and recycled.

Downdraft tables - Downdraft tables are usually associated with plasma or laser cutters. As the machine is cutting, air is drawn downward from below it. This air is then moved through filters, which clean the air and place it back in the shop. They put the air back in to the shop so the building doesn’t have to be continually heated in colder areas of the country.

Updraft Table - An updraft table works the exact opposite. It pulls the air upward, then through a system of filters.

Water Tables - Water tables are used mainly with plasma cutting operations. There is water directly under the piece of metal being cut. The dust and debris of the plasma cutting process is captured by the water table. Over time, the table fills with this debris and must be cleaned out.

Janitorial Services - Some factories maintain a janitorial service that cleans the facility every night. This is usually dependent on the cost in the area the factory is located.

My CNC Story

One day I knew I had a problem. I just spent 4 hours with my plasma cutter in my right hand. I had been cutting out patterns I had traced onto a sheet of metal. These shapes were going to be my new coffee table. Everyone complained to me that I didn’t have a coffee table. I thought, “I’ll show them” and began to build one.

Why make a coffee table out of metal you ask? The quick answer is that I wasn’t much of a woodworker at the time. On the other hand, I used to weld professionally and knew I could make anything out of metal. That is how it all began, making a coffee table out of metal.

Now if you knew me, you know that I can’t just make something normal. My brain is the scheming type that has to do things differently then the norm. I wanted to make a table that would knock people’s socks off. I thought a funky looking table, made out of metal, with casters and lights would do the trick. You know what? It did.

I really had a ball making this table. I mean I had serious fun. So much so that I started to design others. I began showing photos of my work to everyone I knew. On top of that, I was getting good feedback. I had just found a new hobby, furniture making. Who would have ever thought I would pick up furniture making as a hobby.

While making this first table a problem arose. It is the one I mentioned above with my right hand. After plasma cutting all those parts my wrist really began to hurt. While welding professionally there was always the threat of Carpal Tunnel Syndrome. Welders are constantly afflicted by this injury and others because of Repetitive Motion.

If you repeat something over and over and over and over, your body gives out at some point. After cutting up these table parts, I knew I couldn’t go on doing this for a hobby. I knew something would have to change or the new hobby would break my body.

That is when I began investigating Hobby CNC. I call it “Hobby” CNC, because that is how I found it. There were small groups of enthusiasts on the Internet that were building these machines for the fun of it. I thought this was the ticket.

My Initial Thoughts on CNC…

I thought, “If I could build a CNC Plasma Cutting Table?”

I could hook my plasma cutter to it

Create a program of the part I wanted

Cut out multiple parts to my hearts content

Save a lot of time

And Finally…

Save my wrist from the dreaded Carpel Tunnel Syndrome.

I really wasn’t scared of the technology to start with. I grew up in fabrication shops across the Midwest and had seen these machines in action. These machine “Operators” were always held in high esteem at the shop. They always made more Money and always had as much Overtime as they wanted. I decided if they could do it, I could do it.

CNC hobby projects were not cheap at the time. I figured I would have to invest $4,000 - $5,000 to build my table (they have come down considerably). Keep in mind this was in 2000-2001. For some reason that didn’t scare me off. I always liked a good challenge and this was it. With blind faith, I ordered up a CNC Controller and went down to my local steel yard to fill the back of my truck with steel.

Little Did I know…

There was a steep learning curve with CNC. Building a frame for the machine is only a small part of the project. Today it is much easier. The software, components and suppliers are better. There is an entire cottage industry that has sprung up around CNC to support it. Some of the best people in the world make their livings servicing CNC Hobbyist needs.

For some reason I figured if I just build this machine it would spit out parts whenever I wanted it to. Simple, Simple, Simple ran through my head. Over time, I started to get it. I didn’t have a teacher, but I started to learn the ins and out of what I was doing.

Other things I had to learn along the way:

CAD Software

Designing Parts

CAM Software

Preparing parts for machining

Simulating Machining

Machining Basics

Cleaning parts
