The manufacturing landscape is undergoing a significant transformation, driven by persistent labor challenges and an unyielding demand for increased productivity. Many manufacturers grapple with finding a qualified workforce, leading to production bottlenecks and missed opportunities. However, a potent solution is emerging: advanced flexible automation solutions that redefine efficiency and operational capabilities on the shop floor.
As highlighted in the insightful video above featuring industry experts Tony Gunn and Chris Davala from Okuma, embracing automation is no longer a luxury but a strategic imperative. Modern manufacturing automation addresses critical pain points, allowing companies to thrive even amidst staffing difficulties. These innovative systems enable businesses to maximize machine uptime, reduce costly errors, and unlock substantial savings.
Transforming the Workforce: Automation and the 3 Ds
A common misconception is that automation displaces human workers. Instead, as discussed by Chris Davala, it primarily shifts job roles, enhancing the overall quality of work. Automation excels at handling what are often called the “three Ds”: dull, dirty, and dangerous tasks. These repetitive, hazardous, or physically demanding jobs are ideally suited for machines, liberating human operators for more stimulating and value-added responsibilities.
For instance, an operator previously engaged in manually loading heavy parts can transition into a robot programmer or a process optimization specialist. This shift not only improves workplace safety but also elevates job satisfaction and career development for employees. Companies can focus on upskilling their workforce, thereby creating a more engaged and technically proficient team. The implementation of flexible automation solutions allows businesses to overcome labor shortages by optimizing existing human talent.
High-Volume Production with Advanced Gantry Systems
For manufacturers dealing with high-volume production, specialized automation solutions like Okuma’s 2SP-2500 twin spindle horizontal lathe with dual gantry arms offer immense advantages. This system features 16-station stockers, ensuring continuous operation without constant operator intervention. Such setups are particularly beneficial for industries requiring consistent, high-output component manufacturing, such as automotive production or general industrial parts.
These advanced machines can perform sequential operations, such as Op10 and Op20, on a single part or process two different parts simultaneously. The ability to run parts “on and on and on” significantly boosts throughput and reduces cycle times. This level of continuous operation directly translates into higher profitability and a quicker return on investment for the automated system.
Streamlining Grinding with Simple Automation
Historically, grinding operations have often relied on manual loading due to the critical nature of the finishing process. Operators are reluctant to risk damage to parts that already have significant time and money invested. However, solutions like the “Load & Go” system are simplifying this crucial step. This accessible automation makes it easy to integrate robots into grinding cells, ensuring precision and consistency.
The Load & Go is designed for straightforward setup and teaching, allowing it to be quickly deployed in front of almost any machine. This ease of use encourages shops, particularly those new to automation, to adopt robotic loading for grinding. It mitigates the risk of human error in handling high-value components while maintaining the desired surface finish quality.
Navigating High-Mix, Low-Volume Manufacturing with Automation
While high-volume applications clearly benefit from automation, modern flexible automation solutions also cater effectively to high-mix, low-volume environments. The Daifuku cell, featuring 27 different pallets tied to two MB-5000 horizontal machining centers, exemplifies this versatility. Contrary to initial perceptions, such extensive pallet systems are not exclusively for mass production.
This cell allows each pallet to hold a unique job, providing unprecedented flexibility for diverse production schedules. Manufacturers can use their high-value operators during the day to set up and prove out parts on each pallet. The system then runs unattended overnight, achieving “lights-out” manufacturing and dramatically increasing spindle uptime. This strategic approach enhances shop floor efficiency, allowing businesses to accept a wider range of orders and improve overall responsiveness.
The Rise of Collaborative Robots (Cobots)
For smaller shops or specific applications requiring direct human-robot interaction, collaborative robots, or cobots, offer an excellent entry point into automation. Unlike larger industrial robots that require extensive safety enclosures, cobots are designed to work safely alongside humans. Often distinguished by green stripes, these robots feature advanced torque motors that stop instantly upon contact, ensuring operator safety.
The Fanuc cobot showcased in the video, mounted on a mobile cart, demonstrates its practical utility. It can be easily moved and deployed in front of various machines, with simple teaching for new tasks. This adaptability makes cobots ideal for assisting with repetitive, low-risk tasks, freeing operators to focus on more complex programming or quality control functions. Cobots represent a significant advancement in making automation accessible and flexible for a broader range of manufacturing operations.
Optimizing Space and Scheduling with Vertical Pallet Systems
Floor space is often a premium in manufacturing facilities, making compact and efficient automation solutions highly desirable. Fastems cells address this challenge by leveraging vertical space. Although the video discusses a setup with a horseshoe of six pallets, these systems can be configured with multiple rows, such as three rows high, depending on pallet height and specific production needs.
These modular systems, like the Daifuku cell, are perfect for running production during off-hours after daytime setups. Fastems cells incorporate intelligent controllers that can make decisions based on tool availability, machine programs, and even external scheduling software based on due dates. This smart automation reduces the decision-making burden on shop floor personnel, allowing them to focus on machining excellence while the system manages the production flow.
The Undeniable Advantages of Horizontal Machining
Horizontal machining centers offer distinct benefits over traditional vertical setups, particularly regarding chip management and spindle uptime. As Chris explains, with a horizontal spindle, gravity becomes an ally for chip evacuation. Chips fall away from the cutting area and are easily flushed out, preventing buildup on the table. This is a critical advantage for automation, as it ensures a cleaner environment for subsequent operations and reduces the need for manual chip removal.
Furthermore, machines equipped with a two-pallet changer (2APC) allow operators to load new parts on one pallet while the machine continues cutting on the other. This significantly reduces downtime, keeping the spindle active for a much higher percentage of the shift. Horizontal machines also provide the flexibility to machine multiple sides of a part by rotating the tombstone, further enhancing productivity and allowing for complex workholding setups. This design is foundational to achieving truly continuous operation and driving manufacturing efficiency.
Achieving Perfection with Surface Finish Optimization Software
For intricate parts or those requiring extremely high surface quality, software-driven optimization offers incredible value. Okuma’s Surface Guide and Hypersurface technologies demonstrate how digital tools can refine machining processes. Surface Guide analyzes CAM software output to identify imperfections and irregularities in the tool path, providing a visual “color map” of potential issues.
Hypersurface then makes intelligent decisions, smoothing out these inconsistencies to achieve a better, more consistent surface finish. This technology virtually eliminates the costly and time-consuming trial-and-error process of fine-tuning speeds, feeds, and depths of cut. Imagine reducing an 18-hour run time for a single, critical part because the initial program is optimized for perfection. By leveraging these flexible automation solutions, manufacturers can produce higher quality parts “right out of the box,” saving immense amounts of time, material, and labor.
