Definition

All modern manufacturing centers will be running a variety of Computer Numerical Control CNC machines to produce engineered parts. Before CNC machines came to be, manufacturing centers were operated manually by Machinist veterans. Of course, like all things that computers touch, automation soon followed.

These days the only human intervention required for running a CNC machine is loading a program, inserting raw material, and then unloading a finished product.

Over at the Autodesk Pier 9 workshop we have a decent sample of CNC machines, including: CNC Routers These machines cut parts and carve out a variety of shapes with high speed spinning components.

For example, a CNC router used for woodworking can make easy work of cutting plywood into cabinet parts. It can also easily tackle complex decorative engraving on a door panel.

Manual engraving techniques can take months to complete by hand, but one of these machines can complete the same work in hours or days. Plasma cutters are especially useful for cutting through electrically conductive materials like metals. Image Courtesy of Fabricating and Metalworking. Milling Machines These machines chip away at a variety of materials like metal, wood, composites, etc. Milling machines have enormous versatility with a variety of tools that can accomplish specific material and shape requirements.

The overall goal of a milling machine is to remove mass from a raw block of material as efficiently as possible.

Lathes These machines also chip away at raw materials like a milling machine, they just do it differently. A milling machine has a spinning tool and stationary material, where a lathe spins the material and cuts with a stationary tool.

This allows an EDM to melt through nearly anything in a controlled and ultra precise process. Parsons, skillfully operating machines required an enormous amount of training and practice.

A Machinist had to do it all — read blueprints, know which tools to use, define feeds and speeds for specific materials, and carefully cut a part by hand.

Being a Machinist was, and still is, both an art and a science. CA These days, the Modern Machinist is alive and well as man, machine, and software combine to move our industry forward. Skills that used to take 40 years to master can now be conquered in a fraction of the time. What does all this mean for the human element of manufacturing? The role of a Traditional Machinist is shifting.

Being a Machinist was, and still is, both an art and a science. These days, the Modern Machinist is alive and well as man, machine, and software combine to move our industry forward.

Skills that used to take 40 years to master can now be conquered in a fraction of the time. What does all this mean for the human element of manufacturing? The role of a Traditional Machinist is shifting. In a typical workflow the Programmer will hand off his program to the Setup Operator, who will then load the G-code into the machine.

Once the machine is ready to roll, the Operator will then make the part.

In some shops these roles might combine and overlap into the responsibilities of one or two people. Outside of day-to-day machine operations, there is also the Manufacturing Engineer on staff. In a new shop setup, this individual typically establishes systems and determines an ideal manufacturing process.

For existing setups, a Manufacturing Engineer will monitor equipment and product quality while handling other managerial tasks. We have John T. Parsons to thank for introducing a punch card method to program and automate machinery.

Computer-Aided Manufacturing

From there the world of CNC machining started to take off. The idea was to incentive companies to adopt the new technology into their manufacturing process. The earliest CAD and CAM jobs were reserved for expensive automotive and aerospace applications, but today software like Fusion is available for manufacturing shops of any shape and size.

Since its inception, CAM has delivered a ton of improvements to the manufacturing process, including: Of course, these benefits have some trade-offs.

CAM systems and machinery require a massive upfront cost. If this is your first time diving into the world of CAM, I highly encourage you to reach out to a local shop to get an inside tour. Feel the hum of the CNC machines in your feet, or slide your hand across a part fresh out of the machine.

CAM is all about the human touch. Fusion has both.

CAM is very useful. CAM can be more accurate than hand-drawn designs.

Android and Desktop versions are in the making. Exports to the STL file format. Needs WebGL recent browsers!

Similar to Tinkercad. ShapeSmith allows to create 3D printable objects online. Editing objects is fairly difficult unpredictable as of oct. This software is opensource and can be installed on your own server.These features include automatic dimensioning, generation of crosshatched areas, scaling of the drawing, and the capability to develop sectional views and enlarged views of particular path details. Once the G-code is loaded into the machine and an operator hits start, our job is done.

In the case of the CRT image, the quality of the picture is degraded because of lack of resolution and because of losses in the digital-to-analog conversion through: In this and the following two chapters, we consider the application of computer technology to the design of a product.

In NC, there are three basic types of motion control systems: The suitability of NC for these kinds of jobs is the reason for the tremendous growth of numerical control in the metal-working industry over the last 25 years. Hence the user's capability to control the cursor position allows locational data to be entered into the CAD system data base.

When the part is completed, the operator removes it from the machine and loads the next part.
