CNC & Machine Controls

The CNC (computer numerical control) system of a machine tool includes the control unit itself, as well as the motion-control system such as the servomotors, drives and axis positioning devices. These components are part of any CNC machine tool, but they might be bought separately and retrofitted later on older machines that are upgraded or refurbished. Also part of the control system are sensors that may allow the control to make certain real-time decisions during unattended or lightly attended machining processes. These can include probes for measuring the position of the part or machined features, as well as monitoring systems for detecting the presence of the tool or the force that is being exerted in the cut.

FAQ: CNC & Machine Controls

What does CNC stand for?

Computer Numerical Control.

What is CNC?

Computer numerical control (CNC) is the control of machining tools through automation or computer programming. A CNC machine follows coded instructions such as G-code and M-code. These instructions are typically written by a person or by CAD/CAM software. This allows for a highly automated process that can be more efficient than manual machining, providing users with better productivity, speed and accuracy. The most basic function of any CNC machine is automatic, precise, and consistent motion control. All forms of CNC equipment have two or more directions of motion, called axes. These axes can be precisely and automatically positioned along their lengths of travel. The two most common axis types are linear (driven along a straight path) and rotary (driven along a circular path).

How much does a CNC machinist make?

According to the Bureau of Labor Statistics (BLS), the mean annual wage of a CNC tool operator is $44,300 as of May 2020. The median wage is $42,260.

What should new CNC machinists know?

1. Shop safety

First and foremost, newcomers to manufacturing must understand that the shop floor is a dangerous place. You must convey general concerns in two areas: safety equipment that workers use and safety practices to which they must adhere.

2. Shop math

The arithmetic that a typical CNC operator must be able to perform is simple. However, you must ensure that newcomers can use a calculator to add, subtract, multiply and divide.

3. Blueprint reading

Anyone working with CNC machines must be able to interpret a 3D workpiece from a series of 2D views on an engineering drawing. This involves understanding line types (visible, hidden, center, section, etc.) and orthographic projection.

4. Tolerance interpretation

Newcomers must understand that every workpiece attribute has an amount of allowable error, whether it be specified or implied.

5. Measuring devices

Explain the two basic types: fixed and variable gages. Go into detail for any fixed gages your CNC operators use, including go/no-go gages and gages that incorporate a dial indicator.
