Machining Components for Structural Rigidity

In terms of getting the best outcome with regard to general turning operations a client not need seek full blown FEA analysis unless your client is paying you $1000 per hour if you need such detailed element analysis studies feel free to go straight to contact us and not read any further.

In general terms of turning applications, there has been an established set of applications with parameters that make a lot of significant difference to the success of the operations with regard to be it heavy duty roughing large masses or finishing silky smooth surfaces.

Having said that I don't want to be preaching to the converted 

The success of the operation can be determined by a number of inputs in the machining process which are directly related to the properties of such a material. These main machining inputs can be broken down into the following:

• The distance from machine clamp to edge of cutting tool.
• The natural frequency of machine or tool setup.
• The type of cutting applied to a material.
• Is a effective cutting fluid to be used.
• The cutting tool holding arrangement which is unique different for each cutting application, cutting: tool holding insert clamping, insert shape/entering angle and insert geometry/insert grade.

Each of these listed – and especially the way these parameters are applied can have a multiplying effect in terms of a three dimensional vector forces that are driven in a two dimensional space. These limitations can promote or provide some challenges with regard expected machining outcomes based on a specific the properties of a specific material.

Tooling for CNC Machining

Machine Tool

Into the machining field a cutting tool is a tool that remove material from the work piece by a shear deformation. One of the most important qualities that a cutting tool must possess is that it retains its hardness at the high temperatures generated during the cutting process. The most common cutting tool materials used in CNC applications are:

•  HSS
• Cemented carbides
• Ceramics
• Diamond

HSS is alloy of steel containing between 5% and 20% tungsten. It is known by its ability to maintain a cutting edge at the elevated temperatures encountered during machining. Others high-carbon steels can have the same hardness as HSS, but they lose their hardness at the elevated temperatures found at the cutting edges.

Cemented Carbide is another common cutting tool material. Carbides are extremely hard materials and are able to handle a great amount of heat during long periods. Due its hardness carbides must be machined by either grinding or electrical discharge machining. They cost considerably more than their HSS counterparts, but when the productivity gains are measured against cost, carbides are the best choice. 

Ceramic cutting tool materials are formed from sintered aluminum oxides. This material present great performance at higher cutting speeds than cemented carbides and exhibit better wear resistance. This is primarily due to the lower temperatures generated at the tool tip. Its popularity is probably reduce due its deficient capacity for work with intermittent cutting. 

Diamond is natural material with extremely good wear-resistance properties. It resists compression forces twice as well as tungsten carbide and expand very little with heat. For these reasons it can hold very close tolerances during machining and produces an extremely high-quality surface finish.

When machining ferrous components, chemical reaction at high cutting temperatures can cause diamond to revert to its original graphite form. For this reason the cutting tool material is limited to the machining of non-ferrous and non-metallic materials. Polycrystalline diamond is a synthetic diamond mostly used in CNC application due to its super-hard constituents.
