Controlling in the CNC Machining Process
CNC control is the fourth step of the CNC machining process. After the design has been translated into machine language through G-Code, it is now time to put the G-Code and the instructions into motion.
The CNC control stage of the CNC machining process is broken down into three parts namely the CNC control computer, the CNC control software, and the CNC controller itself.
The first part of the CNC control stage in the CNC machining process is the CNC control computer. The CNC control computer doesn’t have to be the newest or fastest computer out there.
There are many CNC computers that are mere 386’s or 486’s. If you aren’t familiar with these 86’s then simply think of them as the computers of the mid nineties. They were the predecessors of the Pentium chips from Intel.
CAM in the CNC Machining Process
CAM is short for Computer Aided Manufacturing. CAM is the third step in the CNC machining process. CAM tries to translate your designs into machine code. In the field of CNC machining, your designs must be understood by a machine.
The CAM stage in the CNC machining process makes this possible.
There are several steps in the CAM stage of the CNC machining process.
The first thing that you’ll have to determine is the kind of machine that you’ll use in your CNC machining process. Are you going to use a cutting machine or a smoothing machine? Identifying the tool that you’ll use is essential. You don’t want a steel driver poking a hole into an object that is tougher than it. You will ruin the tool and your final product.
Using Computer Aided Design in CNC Machining
CAD is short for Computer Aided Design. CAD is one of the essential steps in CNC machining. After designing or making a blueprint of your design in your head or on paper, you’ll have to translate your design into ones and zeroes. In other words, CAD is basically translating your designs so that it can be understood by the computer. Using CAD is essential in the CNC Machining process.
CAD, as an essential phase of CNC machining, goes a long way back. CAD was developed in the early 1960’s. It was used to accurately describe designs. This was during the NC era or the numerically controlled era. Manufacturers wanted to be more exact when they were designing parts, machines, objects, and the like.
Through computers, they discovered that they could increase accuracy and minimize errors dramatically. Prints or blueprints were hand drawn before and there were a lot of inaccuracies then. CAD eliminated a lot of those errors.
CNC Machining Design
CNC machining design is all about thinking and planning about what you’re going to build. Take note that if you are planning properly then you can expect good results. A wise man once said that if you fail to plan, you plan to fail. You don’t want to start doing something without planning properly.
The CNC machining process begins with the designing phase. If you want to do CNC machining properly then you’ll have to make sure that you design things properly first.
There are several things that you have to ask your self when you are in the design phase of CNC machining. Questions that you may have to ask yourself are, how big will this object be? Are you thinking of making an object that is as big as a mouse or an object that is as big as an elephant?
