Climb Milling Vs Conventional Milling – An Ultimate Comparison

Climb milling and conventional milling are some of the most machining techniques. Although the two processes are affective and realistic, there are situations where you should only choose one process.

Today, we will explore some fundamental aspects about these processes:

What is Climb Milling?

Climb milling method involves using the material and the cutting tool both with movement limited to one plane. This machine functions by enabling the piece to move upward onto the cutting tool that is fitted with teeth.

What is Conventional Milling?

In conventional milling, the milling tooling system and workpiece are subjected to opposing movements. It is a previously established method that starts with its width set to zero which widens as operations progress. This method experiences enhanced heat diffusion and the products require finishing procedures.

Comparing Advantages of Climb Milling and Conventional Milling

Climb Milling:

  • This method reduces the need for re-carving as the pieces are placed in the rear of the cutting tool. This ensures that your product has a cleaner finish
  • The rate of wear and tear is greatly reduced in this method. This helps in saving your operational costs as the tools last for extended periods.
  • This method consumes a smaller amount of power, allowing you to save energy compared to similar procedures.
  • Stabilizing equipment and vibrations are greatly decreased in this procedure which is achieved by the equipment applying a down force.
  • Hardening that often occurs during these processes is reduced when utilizing this method

Conventional Milling:

  • The method exerts no tension on your material which results in a fine cut.
  • This method offers more precise wall angling which limits the deformation of smaller materials
  • It is ideal for your applications that involve hard surfaces
  • The method is better suited for applications involving forged, cast, and work-hardened pieces.

Difference Between Climb Milling Vs. Conventional Milling

There are a few limitations that you may encounter when using these methods of milling. These limitations include;

Climb Milling:

  • There is a risk of chipping more so in hardened materials
  • Potential damage such as bending of the tool is likely to occur in operations that involve materials that are larger in size. It can also occur if the application involves fast feeding rates
  • There is a risk of recoil if there is insufficient cutting force
  • This method is not ideal for sturdy materials such as steel.

Conventional Milling:

  • This procedure involves pieces getting deposited in front of the cutter which requires re-carving and the final product typically has a rough surface
  • The products are removed in the inclination of tools which leads to a shorter tool service life and reduced quality of the product.
  • Process produces higher heat which can alter the workpiece besides damaging tooling system
  • Additional stability is required for this process to negate the upward forces generated during operations.

Which is Better between Climb and Conventional Milling

In climb milling, the forming of the desired product is carried out by gradually reducing the width, facilitating heat transfer with the movement of its tools operating with a similar inclination.

The procedure has limited tool bending which produces a better finish with reduced heat produced during the procedure. The downward force produced during this procedure increases the stability of the piece and is much easier on the tools limiting the risk of damage.

Conventional Milling on the other hand utilizes product formation beginning with the least setting which is zero and gradually increases as it proceeds with its tool moving in opposing planes.

In this variation, the piece lands in the rear of the cutter producing a rougher finish that requires reshaping. This method lacks a pulling force which enhances stability and is much easier to control.

Applications of Climb Milling Vs. Conventional Milling

Both milling methods can be utilized for diverse applications. You should therefore consider all the factors when selecting the most suitable method for your applications. The uses of these milling methods include

Applications of Climb Milling

  • Aerospace
  • Precision Machining
