Poor chip formation can lead to increased cutting forces, reduced tool life, and poor surface finish. Here are some tips to help you troubleshoot this issue:

If you want a justification for such convention, I think that it is physical. In a Cartesian plane we usually identify the $x$ axis as horizontal and the $y$ axis as vertical referring to our world where the direction of the gravity is orthogonal (and vertical), with respect to the horizon. And we assign the positive direction of the $x$ axis from left to right and the the positive direction of the $y$ axis from down to up. So it is more simple to assign the positive direction to an angle if it rotate the positive $x$ semi-axis toward the positive $y$ semi-axis and this is the counter clockwise direction.

Another essential technique is trochoidal milling. This method allows for efficient material removal by employing a circular, non-linear tool path. SNMG inserts excel in trochoidal milling due to their strong cutting edges and reduced cutting forces. This results in extended tool life and minimized wear, ultimately leading to decreased production costs.

One advanced technique that utilizes SNMG inserts is high-speed machining (HSM). HSM involves using higher spindle speeds and feed rates, which significantly reduces machining time and improves productivity. SNMG inserts are particularly effective in HSM due to their rigidity and ability to withstand thermal stresses. By optimizing cutting parameters, manufacturers can achieve faster cycle times without sacrificing surface finish quality.

Inspect the cutting tool holder and its alignment. Misalignment can lead to uneven cutting forces and cause the insert to bend.

Check the cutting parameters. Optimize the cutting speed, feed rate, and depth of cut to achieve the desired surface finish.

In conclusion, while both negative and positive inserts have their places in manufacturing, negative inserts can be more cost-effective in long production runs due to their durability, reduced tool changes, and improved efficiency. Manufacturers should weigh the initial investment against the long-term savings and productivity gains to determine the best approach for their specific needs. Ultimately, with careful consideration, negative inserts might just be the smart choice for optimizing production and enhancing profitability.

2023828 — Rough and finish machining stands as pillars of precision, efficiency, and accuracy. This guide delves deep into these two pivotal processes.

The choice of cutting angle should be tailored to the specific application. For instance, a more aggressive cutting angle may be suitable for roughing operations, while a more conservative angle may be better for finishing operations. The cutting angle should also consider the material being machined, with harder materials requiring more conservative angles to reduce tool wear.

Insert bending can occur due to excessive cutting forces, misalignment, or poor tool holder design. To address this issue:

However, it’s essential to consider the initial investment required for negative inserts. The upfront costs may be higher compared to positive inserts, which can deter some manufacturers. However, it is important to evaluate these costs in the context of the entire production run. When considering the reduced maintenance, lower tooling costs, and increased production efficiency, negative inserts often prove to be more economical in the long run.

The cost-effectiveness of shoulder milling cutters can vary depending on the industry. For example, in high-volume production environments, the cost of tooling may be a smaller percentage of the overall production cost, shoulder milling cutters making high-quality cutters more justifiable. Conversely, in industries with tight profit margins, every dollar saved on tooling can have a significant impact on the bottom line.

So, if you want to consider clockwise angles positive, just use a left-handed coordinate system (where $x$ increases right, and $y$ downwards).

Positive angles are counterclockwise only in right-handed coordinate systems, where $y$ axis increases upwards, and $x$ axis right.
