Machining cost reduction strategies

What factors are driving manufacturers to develop cost reduction strategies?

Media (9)

The need to reduce cycle time and machining costs

Manufacturers are always looking for ways to increase overall manufacturing efficiency, but it's more important today than ever before.

Improving cycle times reduces costs in a number of ways:

  • Lowers energy consumption
  • Reduces machine wear and tear
  • Gets the most out of your labor

Savings here can be passed onto the business as a whole, and reduced cycle times could mean increased capacity.

Economic changes

Costs in general are on the rise across the globe. Inflation has been rising in recent years, some raw materials are in short supply, and various geopolitical issues create trade disruptions.

The result is that manufacturing costs can rise unexpectedly over a short period of time. This is why it's essential that your machining is as efficient as it can be, so you’re in a stronger position to absorb increased costs.

Manufacturers are also hunting for ways to get the most out of the machines and equipment they already have to reduce investment in new machining capacity. If a business can find hidden potential in their existing CNC machines, that’s a huge money saver compared to buying additional machine tools.

Where should you start?

CNC simulation software

Slash machine efficiency and downtime

Vericut can simulate fully optimized processes with far greater spindle utilization, resulting in less idle time, and more time for manufacturing.

Manufacturers incur a huge cost from collisions, both in terms of machine damage and production downtime. Vericut Verification simulates machine movements to predict collisions and programming errors before they occur in real life.

This means unplanned downtime, repairs, and tooling damage costs can be avoided prior to actual cutting.

Reduce manual prove-outs

Traditional manual prove-outs can take hours of checking. These are costly from a labor standpoint, but also from a downtime perspective.

So how do you reduce manual prove-outs?
Vericut software allows for virtual prove-outs to reduce physical runs, freeing up machine and personnel time, while also reducing risk.

This means you can be confident you’re making the right cut every time - even on parts you’re running for the very first time.

 

CNC optimization software

Optimize & Improve

Vericut CNC optimization software is the perfect tool for elevating machining efficiency.

It does this by:

  1. Optimizing G-code program outputs from almost any CAM system to reduce unnecessary movements.
  2. Simulating the entire machining process to identify ways to optimize feed rates and tool paths.
  3. Improving overall cutting conditions.

These improvements mean saved energy, maintenance costs, and tool consumption on every part. In the long run, these savings add up, helping to slash overall machining costs. 

Optimize large batches

Vericut Force CNC Optimization software is particularly powerful for optimizing large batches. Simulate one part, validate the code, and scale the results to your low-mix, high-volume manufacturing.

The software also detects potential errors early on, saving costs on mistakes and scrapped parts.

Tool selection and maintenance

Tooling costs

Tooling costs can quickly add up when manufacturing large quantities of components from tough materials. Beyond expected wear and tear, unexpected breakages can also cause scrapped parts and downtime.

It's essential to choose the right tools and maximize their lifespan. This minimizes downtime and wastage. Simulation-based toolpath refinement helps you get the most from your tools while also determining the viability of a more economical tool choice.

Machine operation and maintenance costs

An idle machine is a costly machine, so manufacturers looking to slash machining costs should minimize repairs, downtime, and maintenance.

Again, optimized toolpaths, cutting forces, and feeds will help you get the most from your CNC machines by balancing load and wear with productivity.

Plus, predictive simulation helps engineers identify stress areas that would prematurely degrade machine tools and spindles.

Consider your coolant, too

Coolant is frequently overlooked in cost reduction strategies, but its role is essential.

It is not a ‘set and forget’ aspect of machining. Its concentration, type, and delivery method significantly impact efficiency, component quality, and equipment longevity.

Improper applications can negatively affect tool wear, surface finish, and accuracy. It could even contribute to scrapped parts. In short, it’s costly not to perfect your use of coolant.

Optimizing coolant application is essential:

  • High-pressure and through-spindle coolant systems are a great choice for lowering cutting temperatures. This benefits tool life and feed rates, allowing overall costs to come down.
  • Planning your coolant flow helps flush chips away, lowing the chance of damage.
  • Vericut can help you figure out how coolant interacts with your coolant strategy.

Process optimization and automation

Setup and programming costs

Digital tools are a fast-growing facet of modern manufacturing, and for good reason. Manufacturers who harness intelligent digital technologies find ways to save time others can't, lowering their cost-per-part.

Machining setups are time-consuming and labor-intensive, especially for high-mix, low-volume manufacturing. Vericut simulates setup procedures, allowing for smart adjustments before physical setup.

Plus, with Vericut AUTO-DIFF™, engineers can compare their CAD design models to a simulated CNC machine to check for differences and weaknesses, helping to guarantee components are manufactured right the first time..

Robots and automation

Automation, including physical robots and software-based machine learning, is playing a key role in reducing engineers' machining costs.

Robots automate repetitive and time-intensive tasks like loading, tool changes, and part inspection. These are costly from a labor perspective, but efficient and fast when using robots, meaning your people can put their skills to work on more meaningful tasks.

Automated CNC machines can also operate longer without machinist intervention, even through the night in certain cases. This boosts output per CNC machine, lowering costs.

Many businesses take this concept to the next level with lights-out manufacturing, where manufacturing facilities operate around the clock with minimal human intervention. In this case, robust software and machine learning are a necessity.

These robots are best paired with Vericut simulation software to expedite and improve their deployment across a facility.

In summary: Simulate, choose the right tools, and automate to save on machining

  1. Cutting CNC machining costs doesn’t mean cutting corners. Simulating before you cut and selecting the most cost-effective tools makes a big difference.
  2. By automating wherever possible, manufacturers can boost efficiency, reduce waste, and stay competitive.
  3. Tools like Vericut make these savings scalable and repeatable, empowering your team to make smarter decisions, protect equipment, and deliver high-quality parts at lower cost, every time.
