Time is money. And so is tool wear. Tool wear and tool failure cost shops money in terms of tool replacement, lost production due to downtime for repairs and tool changeovers, additional secondary processes and scrapped parts. Excessive tool wear and tool failure makes for unsustainable manufacturing. Understanding the factors affecting tool wear and how to measure tool wear are crucial to achieving efficient and cost-effective machining.  There is an entire shop full of tool wear types, and successful machining depends on accurate troubleshooting and understanding the role machining parameters play in tool life longevity. Generally, factors causing excessive tool wear include improper speeds and feeds, poor chip evacuation resulting in recutting of chips, improper helix angle and hard workpiece materials. Decreasing spindle speeds to match lower feed rates, using appropriate tool coatings and grades for the work material at hand, choosing the correct helix and relief angles and applying high-pressure coolants can all play a part in reducing tool wear, thereby, extending tool life. Common tool wear conditions include flank wear, crater wear and chipped cutting edges.  Flank wearTool wear, of course, is inescapable, and of all the possibilities, flank wear – a relatively uniform abrasion along the cutting edge – is the most desirable form of tool wear. It is predictable and dependable, so measures can be taken to avoid disaster with adequate tool wear monitoring. Erosion is the primary cause of flank wear as are low cutting speeds. On the other hand, higher temperatures generated by high cutting speeds will create the right conditions for diffusion to occur, which also contributes to flank wear. Optimizing cutting speeds, using harder carbide grades and the correct coolant application will mitigate against flank wear.  Crater wearCrater wear is a common cause of premature insert wear. Heat causes tungsten carbide grains in the substrate to decompose and leech into the chips. This wears a crater into the insert’s rake face. The crater can grow enough to cause the insert flank to chip or cause rapid flank wear. Proper coolant application to control machining temperatures, lower speeds and feeds and the use of a heat-reducing free cutting geometries will minimize crater formation. Chipped cutting edgesMechanical instability in the machine tool setup and inclusions in the workpiece will create small chips in the cutting edge. Processes that involve several interrupted cuts will also cause stress along the cutting edge that will result in chipping. Reducing feeds on entrance and exit along with increased cutting speeds, proper machine tool setup to maximize rigidity and minimize deflection and using a stronger cutting geometry and tougher carbide grade will help prevent chipped cutting edges. Pro tip: Troubleshooting tool breakage and tool failureIn this #SecoTechTalk installment, Seco Product Manager Jay Ball reveals that tool failure and tool breakage are the leading issues in the industry. Solid carbide tools and end mills are not designed to break. So if yours are, you need to consider a holistic approach to examining your machines, tools and processes.

Saw blade milling cutter: used to process deep grooves and cut off workpieces, with more teeth on the circumference. In order to reduce the friction during milling, there are 15’~1° secondary deflection angles on both sides of the cutter teeth. In addition, there are keyway milling cutters, dovetail milling cutters, T-slot milling cutters and various forming milling cutters.

Mechanical instability in the machine tool setup and inclusions in the workpiece will create small chips in the cutting edge. Processes that involve several interrupted cuts will also cause stress along the cutting edge that will result in chipping.

End milling cutter: used for processing grooves and step surfaces, etc. The cutter teeth are on the circumference and end surface, and cannot be fed along the axial direction when working. When the end mill has end teeth passing through the center, it can feed axially.

Cylindrical milling cutter: used for processing planes on horizontal milling machines. The cutter teeth are distributed on the circumference of the milling cutter. According to the tooth shape, they are divided into straight teeth and spiral teeth. According to the number of teeth, there are two types: coarse teeth and fine teeth. The helical coarse-tooth milling cutter has few teeth, high tooth strength and large chip space, suitable for rough machining; fine-tooth milling cutter is suitable for finishing.

Face milling cutter: It is used to process plane on vertical milling machine, face milling machine or gantry milling machine. There are cutter teeth on the end face and circumference, as well as coarse and fine teeth. Its structure has three types: integral type, insert type and indexable type.

Milling cutter is a kind of rotary cutter mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. When working, each cutter tooth intermittently cuts off the margin of the workpiece. There are several common types of milling cutters, such as cylindrical milling cutters, face milling cutters, end mills, face milling cutters, angle milling cutters, saw blade milling cutters, and T-shaped milling cutters:
