Humankind has consistently
demonstrated our ability to do and invent amazing things using only our hands
and simple tools, but the greatest invention by far has come in the last half
century when we developed computers. Computers have the power to command and
control other tools with a preciseness that was before unthinkable. This was
particularly groundbreaking for the manufacturing industry. For the manufacturing
world, the invention of computer technology and accompanying software changed
the game for precision, speed, and strength. Today, computer numerical control
(CNC) machining equipment is commonplace on many operations floors guided by
advanced program software. At Bowman Tool & Machining (BTM), our team of
skilled, expert engineers and machinists utilize CNC machining in our
state-of-the-art facilities to provide the highest-quality
precision manufacturing services possible to our clients.
numerical control was first utilized in some capacity with the tape-punch
servomechanisms of the 1940s and 1950s. While effective in its own right, this
analog method of manufacturing cannot compare to today’s digital high-powered
computer intelligence. With a 150,000 square foot manufacturing space, BTM
houses over 50 CNC machining centers and additional automated equipment that serves
as a prime example of what computer numerical control can do for the custom
For over 40
years, BTM has worked to continue embracing advances and innovations in CNC
machining. Today we take projects of all shapes and sizes into our experienced
hands and, with an engineering-driven approach, manufacture components and
parts with unparalleled quality. Even with our highly skilled team and our efficient
production procedures, BTM’s level of excellence would not be possible without
our pillar of strength: CNC machining.
“CNC Machining is a
process used in the manufacturing sector that involves the use of computers to
control machine tools.
Tools that can be controlled in this manner include lathes, mills, routers and
grinders. The CNC in CNC Machining stands for Computer
part starts out as a block of raw material. Precision machining cuts the raw material to
specifications that become the individual part.
makes this process both accurate and more efficient. You program the machine
once, and it repeats the process as many times as you need it to.
what can be accomplished with our advanced CNC machining capabilities, it’s
important to recognize a few basic facts about the process.
CNC machining relies
on the preprogramming of tool movement into our manufacturing-specific
software. This programming system is based on movement across three axes: x, y,
and z (respectively: horizontal, vertical, and depth movement). Our engineers
program a CNC operation based on the data specific to a digital part design
using the geometry built with our computer-aided design (CAD) software and
translated through computer-aided manufacturing (CAM) software.
This programming ability works well for rapid prototyping and
machining complex parts because both require an extremely accurate process to
The patterns of
movement a CNC machine follows are determined by the instruction code
programmed in the common CNC language g-code. G-code communicates the full
process for a machining operation, including speed, feed rate, and full range
machining process is also directed in varying ways depending on whether it runs
on a closed-loop or an open-loop system. When open, the CNC signal runs in one
direction between the control and the motor. When closed, the control receives
constant feedback from a cyclical loop. While a CNC machine can operate on
either system, a closed-loop may be more effective in correcting errors in the machining
process as it receives feedback information on speed, momentum, and position.
CNC Machining Tools:

utilize several types of machining tools for a comprehensive fabrication
approach to manufacturing any given part.
operate with CNC mills and lathes. Our CNC milling centers offer machining at
several depths along the x-axis in addition to horizontal and vertical movement
along the x and y axes. Our CNC lathes provide both x and y axis movement
cutting on a changeable circular index. Both mill and lathe movements are
programmed through G-code specifications.
When you cut a
part using a CNC milling machines, the tool itself moves around the part and
the part is stationary. The computer control will guide the machine to cut the
part along a predetermined path.
are more suitable for complex parts with intricate cut patterns. The versatility of these
machines means they can cut virtually any part.
We use these
machines as part of the contract manufacturing process to machine parts with
predefined specifications and we can also use them in the prototype to
production process for newly invented parts.
CNC lathes work
in the exact opposite fashion. The part rotates around the tool. This process
is commonly used for cylindrical parts.
You can create
the same parts using a milling machine as you can with a lathe, but the process
for creating cylindrical parts and other parts that favor this type of machine
is much more streamlined using a lathe.

their part and have the capabilities to do it.
Benefits of CNC Machining
Everything we do is for our clients. While there are many
benefits of CNC machining for us as manufacturers, all of them translate into
benefits for our clients.
Precision: CNC machining
can achieve accuracy within 1/1000th, virtually eliminating human
error. This accuracy is also able to be replicated, allowing for consistent uniformity
in parts and components, resulting in higher quality for our clients.
Speed: We understand the importance of getting your
components on time. CNC machines can create uniform parts, quickly. Not only
can they outpace their traditional counterparts, CNC machines can work around
the clock, never needing a break, except for routine maintenance. This means
the turnaround time for clients is less and there’s less disruption in the line of production.
Low Cost: While the initial investment in CNC machines is higher, in
the long run it’s worth it. For high-quantity projects, CNC machining is more
cost effective than traditional machining. CNC machining is efficient, precise,
quick, and requires little labor. All of this adds up to serious savings for our
Versatility: If you can dream
it, CNC machines can create it. CNC machines are highly versatile and can
include a variety of accessories and features that expand their machining
capabilities. They’re capable of creating complex components that would otherwise
be impossible by manual machines and compatible with
a variety of materials including aluminum, brass, copper, titanium, wood, and
plastic. Between our prototyping design and development services and
our CNC machining capabilities, we’re able to provide unique solutions for our clients.
machining process is almost completely automated from design to programming to
operation. Because BTM’s skilled engineers utilize advanced prototyping software
in the design process and seamlessly translate CAD files into CAM and CNC systems,
our CNC machining operations are the single most efficient and accurate methods
of custom manufacturing.
