Laser Cutter

An Inside Look at CNC Machining

The reason why CNC tools are so effective is due to their accuracy, efficiency and productivity. A CNC laser cutter machine is relatively easy to keep up and running upon initial setup. Even the work piece loading process has been automated in some companies. Most of the time CNC operators are required to complete other tasks related to the operations of the CNC. Some of these tasks include measuring work pieces and making adjustments to keep the machine running at maximum efficiency.

An Inside Look at CNC Machining

Most people you talk to in your life will never have even heard of the term CNC machining before. Little do they know that the CNC process has probably touched their life in one way or another. If you work in manufacturing, it is more likely that you have heard of the term and you’ll most likely be dealing with a CNC at some point. Everything that an operator is able to do with conventional machine tools is programmable with a CNC laser cutter machine. Next we take a closer look at CNC machines and their operations.

An Inside Look at CNC Machining

With CNC touching so many aspects of manufacturing and large fabrication, many machining processes now incorporate the use of CNC. We now take a look at how CNC machining affects the world of metal removal and metal fabrication. When removing metal the processes of facing, boring, turning, grooving, knurling, and threading are done with CNC turning centers. There are many variations of these machines which include, CNC milling machines, CNC drill and tap centers, and CNC lathes. Outside diameter grinding and internal diameter grinding would be completed on CNC grinders.

If a CNC could only move a work piece in two directional axes its functionality would be severely limited. This is why almost all CNC machines are programmed to operate in several other ways. The actual machine type has to do with its programmable accessories as well. Some of these accessories include the following: An automatic tool changer allows the tool to be automatically placed in the spindle when machining. The speed of the spindle can easily be specified and the spindle can be turned in two directions. In addition, many machining operations must have coolant for lubrication purposes.

When using CNC in association to metal fabrication, think of a metal filing cabinet. All of the initial components are made of steel sheets. These sheets are sheared to a certain size and holes are placed in specific locations. The sheets are then formed to their final shapes. Many CNC-like procedures are now used for processes that describe a series of movements and operations. Some of these include laser cutting, welding, friction stir welding, ultrasonic welding, plasma cutting, forming, and fabric cutting, routing and even sawing.

CNC Operators or Programmers Rules Before Running Any CNC Machine

CNC Operators or Programmers Rules Before Running Any CNC Machine

Computer Numerical Control (CNC) Operators are responsible for any CNC laser cutter machine crash when they are in operation. Crashes happen frequently on the shop floor and are often catastrophic and costly. Accidents are usually due to the lack of skilled CNC Operators or well-trained CNC Operators within the manufacturing industry.

Crashes are often due to the following errors caused by the CNC Operators:

– Lack understanding of CNC motion in use
– Lack understanding of Spindle travel reference
– Lack understanding of CNC coordinates
– Lack understanding of Zero position
– Lack understanding of CNC axes travel limits

Here are few tips to help you to quickly check before running any CNC to manufacture a part.

– As a CNC Operator, you are responsible for the result after completing the process in the manufacturing of a particular part from the part print to the CNC program and finally the CNC motion. These steps must be accurately checked and rechecked to avoid any error slipping through.

CNC Operators or Programmers Rules Before Running Any CNC Machine

– All CNC laser cutter machines are designed for several applications such as turning, milling, grinding and drilling. But all CNC machines have two or more directions of movement or axis, this means the more axis the machine has the more complex the CNC machine, hence a 3-axis milling machine is considered to be less complex than a 5-axis milling machine.

– A CNC Operator is responsible for placing the part onto the table and making sure the setting of XYZ axis’ to datum are recorded and stored into work offset registry (i.e. G54 TO G59 in Haas machines) this will enable the part that’s being manufactured to be located at any point within the table by simply setting the x and y value to zero then the machine to zero (i.e G28 or G29 in a Haas machine).

– A CNC Operator must understand that even though the table moves when the part is being manufactured the motion of the machine is always measured from the spindle view not from the table view. Hence we must always refer to the spindle center point location when taking measurement.

– A CNC Operator must not confuse between the two coordinates systems (i.e. the machine coordinates systems and the work coordinates systems). The machine coordinates system is set by the manufacturer of that particular machine and cannot be changed and is within the machine itself. It is, therefore, the reference coordinate system from which all else is referenced. The location of XYZ machine origin within the laser cutter machine may be different depending on the machines manufacturers. Hence it is advised to check the machine manufacturer’s catalog for precise instructions.

– Zero position, this command zero all axis i. e homing the machine, this command returns all axes to their limited position. The order of the axis movement is set by the machine manufacturers. It must be noted that each machine has different methods to be Home. Again you must refer to the machines manual guide provided by the manufacturer of that machine.

A CNC Operator or Programmer must know the total limits that each laser cutter machine axis is allowed to move; in general this depends on the manufacturer of the machine. However, a skilled CNC Operator or Programmer can easily identify these parameters as they decide the fate of the manufacturing process.

CNC Machine Basics

CNC Machine Basics

Variables on the operation of CNC laser cutter machines will vary from one CNC type to another. CNC machines are available is several different types. Anything from lathe machines to water jet machines, so the mechanics of each different machine will be different; however, the basics work primarily for all the different CNC machine types.

CNC machine basics should be called benefits. The benefits of a CNC laser cutter machine are the same for each machine as it is for every company who owns one. Computer-aided technology is a wonderful thing. A CNC machine offers that benefit to its owners. Intervention by the worker is needed less, as the machine does all of the work once the software is programmed to the specifications desired. The machine will continue to run until the process is complete, all completely unmanned. This frees up the worker to perform other tasks if necessary.

CNC laser cutter machines offer these benefits:

o Fewer mistakes caused by human error
o Consistent machining each and every time
o Precise machining each and every time
o Reduced operator fatigue, if any at all
o Frees up the operator to perform other tasks
o Speeds up production
o Reduces waste
o Skill levels to operate machine is lower (must know how to program the software)

Overall here’s just a few of the benefits that CNC machines have to offer. Keep in mind that the benefits are also relative to the type of CNC machine that’s being operated and the tooling it’s equipped with.

CNC Machine Basics

Switching from the production of one product to another is very simple and can save the business a lot of time. In the past it could have taken a day to several days to set a machine up to make the proper cuts that are needed for the order. Now, with the CNC machines, set up time is drastically reduced. It’s pretty much as simple as loading a different software program.

CNC laser cutter machines operate not only through a computer software program; they are motion controlled and operate on several different axis’ depending upon the type of the machine. The CNC lathe machine operates on the X and Y axis unlike the 5 axis machines that are now available on the market. The more axes that the machine operates on, the more delicate and precise the cuts; the more creative you can become in your projects, and the more you can offer fabrication services. The CNC machines can pretty much do it all without human intervention other than through the use of the computer software.

No more hand wheels and joy sticks causing the motion those most machining tools require. Now, the computer, through the software program, instructs the machine on what exactly to do and the machine continues to perform until the specifications or guidelines have been reached, upon which time it discontinues operation for that sheet of material. The human intervention that is needed with a CNC laser cutter machine is the programming. Programming for the machines is written in sentence like structures that are in G-code. This code tells the different axis’ what to do and completely controls all aspects of the laser cutter machine.

Alternatively, many shops also utilize a laser cutter along with their cnc router.  They are typically easier to operate and offer much greater precision.  If you’re interested check out the laser cutting retailer: Boss Lasers.
