Manual Aerospace Drills for Industry 4.0

Stay relevant with manual aerospace drills for fuselage assembly despite increasing automation in the industry

Is your company apprehensive about investing in manual aerospace drills? Most aerospace companies are considering full automation to keep up with the increasing demand for aircraft manufacturing.  So far, this still remains a distant reality [1]. There is simply too much data [2] needed to automate the machine - and to match the skill of an experienced operator. 

In this article, we will explore the benefits of having higher-quality and more reliable, manually operated drills from the fuselage to the final assembly of aerospace manufacturers and suppliers in the face of increasing automation in the industry.

Importance of proper drilling in fuselage integrity

The parts of an aircraft[3] are commonly made from a composite material of carbon fiber reinforced polymer or CFRP and sheets of light metals, such as aluminum or titanium alloys. Holes are drilled through these parts, so they can be joined in the later stages of assembly. 

A CFRP composite material is extremely durable, but drilling through it could cause the layers to separate at the hole opening, creating a weak spot that is vulnerable to the repeated cycles[4] of pressurizing then depressurizing, which an aircraft is frequently subjected to. That is why proper techniques such as one-shot drilling or OSD are needed to prevent the layers from delaminating[5] and compromising structural integrity.

The drilling operation[6] is critical in the assembly of the fuselage due to the high number of holes needed for the riveting stage. Different types of drills are needed to make different types of holes, each with its own purpose, and all critical for the overall performance of the aircraft.

How manual drilling is still relevant despite the 4th revolution

The last several decades have shown a steady increase in the demand for aircrafts and no signs of slowing down. In fact, an increase of 45%[7] in the size of the aircraft fleet for North America alone is expected in the next two decades. 

That is why today’s aerospace industry is continuously looking for the best production system that balances cost, energy, and social and environmental impacts. This includes manufacturers trying to fully automate fuselage assembly. 

Significant leaps have been made in the digitalization of the aerospace manufacturing industry. However, machines still cannot match the dexterity and precision of manual drilling. Further, manual drilling cannot be eliminated entirely, at least in some cases. [8] Thus, the significance of reliable manual aerospace drills for the aeronautical sector cannot be downplayed despite the imminent automation from the fourth industrial revolution.

In an effort to close the gap between manual and automated drills, tools manufacturers are making increasingly smarter manual drills. These advanced tools are capable of minimizing operator error and dramatically improving hole quality. They are also easier to handle and safer to use, which increases operator productivity holistically.   

Now that we have explored the limitations of fully automated drilling and assembly, we will explore the best manual-drilling options. These options are job-specific and take into account reliability and long term cost savings.

Different types of aerospace drills used in the fuselage assembly

The production of an aircraft's frame involves a complex process[9] of drilling, countersinking, and riveting, which is a challenge so far for full automation. It requires different types of drills, some of which will be discussed in this section.

  • Electric handheld drill - The electric handheld drill is a battery drill perfect for any stage in the fuselage assembly, with a programmable trigger that keeps drilling speed constant. It is packed with countless other features to enhance operator productivity. In essence, it’s a smart manual drill.   

Battery drill EBB

Safety - As a cordless aerospace drill, it eliminates the risk of injury from trips and falls. Its size and weight are ideal for gripping and hours of effortless drilling with no wrist injury.

Cost Savings - The drill has five speed settings, which can be adjusted through an intuitive HMI for a wider range of applications from a single tool. Its handle length and design ensures perpendicularity while drilling. In addition, it has an LED indicator that monitors energy and cutter usage, so that you can optimize cutter life.   

Energy Efficiency - It is powered by an 18V or 36V battery with a switchable position so that you can get into hard-to-reach spaces. 

Social and Environmental Impacts - It is 14 times quieter than a pneumatic drill, which leads to less disruption in the work area and its surroundings, and has better ergonomics to ensure the health of its operator.

  • Advanced drilling unit - The advanced drilling unit/PFD (Positive Feed Drill) can be used for a wide range of high-speed and heavy-duty drilling from component manufacturing to final assembly.

Advanced Drilling Unit PFD 1100

Safety - Each unit has an emergency stop button within arm’s reach of the operator so that work can be immediately stopped if needed. 

Cost Savings - It has a distinctive modular design, which means only one motor is needed to drive several drilling components for a wide range of applications in one-shot drilling and countersinking.  

Energy Efficiency - It has a built-in lubrication pump for delivering the right amount of coolant on the cutting tool tip, ensuring high efficiency every time you drill.

Social Impact – It has an easy configuration for faster module changeover, which is better for operator ergonomics and working conditions.

Environmental Effects - It is energy efficient to reduce carbon emissions and other environmental footprints from product use.

  • Handheld angle drill - This is a heavy-duty handheld drill built with a shorter head length, perfect for drilling holes in tight spaces.

Safety - The operator can direct side exhaust as he sees fit. It is also designed for comfort, safety, and ease of use.  

Cost Savings - It has a lubrication-free motor, which means less maintenance is needed. 

Energy Efficiency - It has a low runout for higher precision and a low operating cost. 

Social Impact - It has reduced head length for better ergonomics in cramped spaces.

Environmental Effects - It consumes less air, which conserves energy.

  • Pneumatic handheld drill - The pneumatic handheld drill is built for a wide range of applications in fuselage and final assembly. Its rubber pistol grip reduces vibrations and temperature fluctuations for a consistent hole quality every time you drill.
