What is Tooling in Machining?

A machinist working in a busy machine shop, was having trouble machining a complex aerospace part. She changed to a different tool, and not only did she solve the machining problem, but she also made the part more accurate and faster to produce. That incident really showed me the power of tooling to transform machining processes.

What is tooling in machining?

Tooling in machining refers to the cutting tools, molds, dies, and fixtures used in machine shops to shape, form, or fabricate parts from different materials. These tools are critical for achieving precision and efficiency, which ultimately determines the quality and feasibility of the final product.

Tooling is not just about shaping materials. It is critical to the entire manufacturing process across different industries, such as automotive, aerospace, and more. With the right tooling, manufacturers can increase productivity, maintain quality standards, and reduce production costs. It is a critical part of industrial operations.

What is workholding and why is it important?

Workholding devices, such as clamps, vises, and jigs, are critical for securing the workpiece during machining. They play a significant role in improving productivity by allowing for quick setups and changes, ensuring product quality by maintaining stability during machining, and reducing costs by minimizing waste and errors. For example, in CNC milling, precise workholding is crucial for achieving the high levels of accuracy required in aerospace part fabrication.

What factors should I consider when selecting workholding?

Choosing the right workholding depends on several factors including the type of material being machined, the complexity of the machining operation, and the expected throughput. For instance, softer materials might require gentler clamping to prevent deformation, while complex operations may need custom fixtures to support unique geometries.

How do you maintain and manage tooling?

Maintaining your tooling involves regular inspections and cleaning to prevent wear and tear that can degrade precision. Proper storage solutions, such as rack systems and protective coverings, are also essential to manage tooling and extend its life. This ensures that tools are protected from environmental factors that could cause rust or degradation.

How do you evaluate tooling performance?

Evaluating tooling performance can involve analyzing production throughput, inspecting the quality of finished parts, and monitoring tool wear over time. Regular performance checks help you make informed decisions about tool replacements or adjustments needed to maintain optimal operation.

How do I know if the tooling is right for the job?

You have to look at the material properties, the precision you need, and the complexity of the part geometry. You also have to run some parts and do some prototyping to see if the tooling you’ve selected can meet your production demands.

What do you see happening in tooling in the future?

You’re going to see a lot more automation and digitalization. Automated tool changers and digitally controlled setup adjustments are going to make us more precise and reduce our downtime. You’re also going to see more of a focus on sustainability and environmental protection. People are going to come up with ways to make tooling that doesn’t waste as much and doesn’t use as much energy.

In conclusion, tooling is important and you need to know what you’re doing. As Sarah’s story illustrates, when you get the right tooling and use it correctly, you can solve immediate problems and make your operation better. If you want to keep winning and keep your job, you have to stay on top of tooling technology and you have to manage your tools better.
