CNC milling machines enable users to precision-cut hard metals such as steel or aluminum. They remove metal by rotating a multi-toothed cutter into a moving work piece. A CNC vertical milling machine (VMC) has a vertical spindle and an X-Y table that allows the work piece to move into position. A horizontal milling machine (HMC) has an X-Y table for work piece positioning and horizontally mounted cutters. A universal milling machine (UMC) has capabilities for either vertical or horizontal milling.

Milling machines come in various sizes for a range of applications. Machinists often use industrial CNC milling machines for engine components. Metal workers can use a small CNC milling machine for jewelry and other decorative metal objects. When purchasing a CNC milling machine, you'll find many brands and models to choose from. Evaluate them carefully to find the one you need.

1. Identify your needs in a CNC milling machine. What you're going to use your machine to make should determine the kind you buy.

2. Decide whether you want to look at new or used CNC milling machines. New milling machines cost more.

3. Consider leasing a CNC milling machine. Leasing has some advantages, like affordable monthly payments.

G codes

These codes (also called preparatory codes) are functions in the CNC programming language that begin with the alphabet letter G. A G code provides instructions to the machine about the action or movement to be performed. G codes can initiate various actions such as movement of tool or component, changing tools, and setting a tool or tool set.

I recommend: You can read through the glossary of technical terms at MachineWorks, a developer of NC simulation and verification technology.

Program zero

In CNC milling machines, positioning of a component is very important, as all milling operations are carried out considering the initial position of the component and tools. Program zero is the initial reference position of a component for any milling operation to be performed.

I recommend: Toolingu.com, a reputable provider of online training programs, offers a glossary of technical terms, such as G codes and program zero.

Canned cycle

This indicates a program for a set of operations that is started by a single G code. While writing a program for machining a complicated component, canned cycles act as shortcuts for the programmer.

I recommend: For definition of this key term, read through the glossary of technical terms at MicroSystemsGeorgia.com.

Tool path

As the name indicates, a tool path is the set of co-ordinates, along which the tool moves for completing the machining operation.

I recommend: To understand the definition of a tool path, read through the CNC glossary at CNCInformation.com.

Rotary tables

A rotary table is an important component of CNC milling machines. In a CNC milling machine, a rotary table is controlled using a stepper motor and milling software.

I recommend: To learn more about rotary tables and their applications in milling machines, read through information at Sherline Products.

Milling cutters

A milling cutter is an important component of a CNC milling machine, as the performance of the milling machine depends upon it. Selection of the milling cutter depends upon requirements of surface finish, cutting speed and material of the component.

I recommend: To learn more about milling cutters and their types, read through information at Tool Masters, a manufacturer of industrial cutting tools.

Tolerances

Tolerance is the permissible variation of dimensions of a machined component from the design dimensions. This is an important aspect of a component and before buying or renting a CNC milling machine, you will need to assess your tolerance requirements.

I recommend: eMachineShop.com provides detailed information about tolerances and their importance.

While a CNC milling machine has more safety features than a regular mill, there are still safety precautions everyone who operates your milling machines CNC control should take. In fact, training should be included in the CNC milling machine price if at all possible. Regardless of whether you have a benchtop CNC milling machine or a large model, the same safety precautions should apply.

Because CNC milling machines are highly sophisticated pieces of equipment, anyone who touches them should have basic training in their operation. This training should include safety precautions. Also, anyone operating the milling machines CNC control should:

1. Wear protective eyewear suitable for use around a CNC milling machine.

2. Tuck loose fabric such as shirttails in to pants.

3. Wear steel-toed safety shoes or boots.

Know the CNC milling machines in the shop

While no one can know how to operate every CNC milling machine, everyone in your shop should have basic instruction on operating the equipment safely. This may mean a course at a local vocational school will need to be arranged. Another option would be to hire a safety specialist come to your shop to train everyone. A third option is to have one of your staff members attend train-the-trainer classes, then teach everyone else.

I recommend: Take the CNC milling machines safety test from Fox Valley Technical College. You can also study the diagram of a table top CNC milling machine at TechnologyStudent.com. Be sure you can identify the safety features on the CNC milling machine.

Post safety rules near the CNC milling machines

Draw up a set of rules you expect your employees to abide by on a daily basis. Post those rules in a prominent place near the CNC milling machine. Since shops sometimes get dusty, it's a good idea to laminate the rules so that they remain visible for a longer period of time. Replace the safety sign when necessary.

I recommend: The Canadian Centre for Occupational Health and Safety has a list of safety checkpoints you should go over before you operate tree milling machines. Read and adapt the CNC vertical milling machine safety checklist from Rensselaer Polytechnic for your business.

Maintain safety guards on CNC tree milling machines

If a safety guard breaks, replace it immediately. If you don't have one on hand, do not use the machine until it's replacement is on the machine.

I recommend: Buy safety guards for your tree vertical milling machine from Flexbar. You can also retrofit safety guards on used CNC milling machines. Put safety guards from Rockford Systems in place on your tree CNC milling machine.
