When chips are not managed during machining parts, scrap occurs.

You can always bet on LeBlond when machining gets tough. LeBlond helps when the chips are down. In this case, literally when chips are cut from a workpiece. Chips are an important aspect of metalworking. Milling, drilling, boring and turning all throw metal chips. Controlling and clearing chips while machining metal parts is crucial for maintaining machining efficiency, ensuring safety, identifying possible tooling issues, and producing high-quality finished products.

Here are some best practices for machinists to effectively clear chips:

1. High-Pressure Coolant Systems: Efficiently remove chips from the cutting zone with coolant systems. The coolant flow maintains a consistent temperature of the tool and workpiece plus flushes chips away from the cutting area. Ensure coolant is directed precisely at the cutting interface to maximize its chip-clearing effectiveness. Contact your coolant supplier for exact products to meet your machining needs.
2. Air Jets and Nozzles: Use compressed air jets to blow chips away from the cutting area. This is particularly effective in dry machining operations. Consider using programmable air nozzles directed to different parts of the workpiece during the machining cycle.
3. Chip Conveyors and Augers: Integrate chip conveyors into the machining setup to automatically transport chips away from the work area. Use augers to collect and move chips out of the machine, particularly for larger volume operations. Implement robotic systems for automated chip removal, reducing manual intervention and improving consistency.
4. Chip Breakers and Tool Maintenance: Use cutting tools with built-in chip breakers to produce smaller, more manageable chips. Regularly inspect and maintain cutting tools to ensure they are sharp and in good condition, reducing the likelihood of long, stringy chips.
5. Machine Enclosures and Guards: Safety first. Use machine enclosures to contain chips and coolant within the work area, preventing them from spreading to the surrounding environment. Install chip guards and barriers to protect operators and equipment from flying chips.
6. Chip Management Systems: Use centrifugal chip separators to remove chips from coolant, ensuring the coolant remains clean and effective. For ferrous materials, magnetic conveyors effectively remove and transport chips.
7. Automated Wash Stations and Vibratory Deburring: Use automated wash stations to clean parts and remove chips after machining operations. Vibratory deburring machines also smooth parts and remove any chip buildup on finished pieces.

Implementing these best practices significantly improves the efficiency of chip removal, enhances safety, and maintains the quality of machined parts.

Get Creative When Machine Shop Floors Get Cramped

Precautions Machinists Can Take to Avoid Common Machinability and Material Selection Pitfalls

Squeezing into an old pair of jeans that previously fit comfortably but are now too tight for your waistline is similar to a limited workspace some shop machinists experience. At one time, the shop floor accommodated all the machines and parts inventory. However, shop floorspace becomes a premium with new business growth, increased orders, customer inventory storage and additional machines. What’s a machinist to do?

There are several strategies machinists can employ to overcome these shop floor constraints:

1. Organization and Efficiency: Maximizing the use of available space through efficient organization is crucial. Streamlining floor space includes implementing lean manufacturing principles, organizing tools and materials effectively, and ensuring that workstations are kept tidy.
2. Modular Workstations: Using modular workstations and tooling setups can help optimize space usage. Machinists can configure these setups based on the specific requirements of each job, allowing for flexibility within a limited workspace.
3. Vertical Storage: Utilizing vertical storage solutions, such as Kanban shelving units or pegboards, can free up valuable floor space. Machinists can store tools, materials, and workpieces vertically to maximize the use of available area.
4. Just-in-Time Inventory: Implementing a just-in-time inventory system keeps necessary inventory on hand. Machinists can minimize storage requirements on premises for part assembly (see the next point).
5. Off-Site Storage: If space constraints are severe, machinists may consider utilizing off-site storage facilities for less frequently used tools, materials, or equipment. Parts manufacturers offer suppliers this option to help free up space on the shop floor for essential operations.
6. Mobile Equipment: Investing in mobile equipment, such as carts or tool chests, can enable machinists to move tools and materials around the shop more easily to help optimize workspace usage.
7. Multi-Functional Equipment: Choosing multi-functional equipment and tools can help save space in a machine shop. For example, investing in a CNC machine that can perform multiple operations or using multi-axis machining centers can help reduce the need for additional machinery.
8. Regular Maintenance and Cleaning: It has been said, “A clean desk is a sign of a cluttered mind.” However, maintaining a clean and organized workspace is essential for maximizing efficiency in a machine shop. Regularly cleaning machines, workstations, and storage areas can help prevent clutter from accumulating and optimize available space. Plus, clean workstations reduce the risk of injuries or errors.

Growing pains present themselves in many ways for a manufacturer. Limited shop floor space is a good problem to have. Once faced with cramped spaces, there are multiple opportunities to get creative with floor space. The above options may be necessary if moving to a larger facility is not in the forecast.

Best Solutions for Common Machinability and Material Selection Pain Points

Precautions Machinists Can Take to Avoid Common Machinability and Material Selection Pitfalls

​

Knowing the right materials to use when machining metal parts for a specific application is vital for efficient production. Selecting the most appropriate metal or alloy can make or break a parts order. Not only does the right material selection extend tool life, but it improves cutting and finishing. Improving machinability and material selection for manufacturing high-volume metal parts involves addressing several key issues and implementing corresponding solutions:

1. Machinability

Challenge

Machinability refers to the ease with which a material can be machined into the desired shape and dimensions. Poor machinability can lead to increased production costs, tool wear, and reduced efficiency.

Solutions

• Optimize cutting parameters, such as cutting speed, feed rate, and depth of cut to improve machining efficiency and surface finish.
• Implement advanced cutting tools and coatings designed for specific materials and machining operations. Look for carbide inserts, ceramic inserts, polycrystalline diamond, cubic boron nitride, or other high-performance tools.
• Use computer-aided manufacturing (CAM) software to generate optimized tool paths and machining strategies.
• Experience goes a long way. Train operators and machinists on proper machining techniques and tool maintenance to maximize performance and tool life.

2. Material Selection

Challenge

Choosing the right material to achieve the desired strength, durability, and corrosion resistance.

Solutions

• Conduct thorough material analysis to identify the most suitable alloys or metals for the specific application.
• Use materials databases and simulation tools to assess material properties and performance under different conditions.
• Consider factors such as cost, availability, environmental impact, and recyclability when selecting materials.
• Collaborate with material suppliers and experts to explore innovative materials tailored to the application requirements.

By addressing these issues and implementing the corresponding solutions, manufacturers can improve material selection and machinability for producing high-volume metal parts efficiently and cost-effectively.
