Favor Laser’s XO high-performance laser cutting machine is based on custom CNC hardware and software from NUM Corp. The laser cutter is capable of producing very small or very large parts from sheet metal, with a feed rate ranging to 60 m/min. All Favor Laser machines are based on a “flying optics” system, which supports the sheet metal on a stationary table while the cutting head directing the laser beam moves horizontally above the surface of the sheet. Because the cutting head has a low and constant mass, this approach is said to facilitate faster and more precise positioning than laser cutters that move the workpiece beneath a static laser beam using a motion control system.

Favor Laser chose NUM’s Flexium 68 CNC system for CCMT Insert the XO machine for both its hardware compatibility and software functionality designed to simplify application programming. In particular, the software’s Dynamic Operator (DO) function supports programming that dynamically controls the gap between the cutting head and the workpiece. According to the company, the DO function’s fast calculation and communication abilities enable the integration of event-driven machine cycles into the real-time CNC kernel.

All motion control elements of the XO laser cutter are also supplied by NUM. In addition to the motors, drives and Flexium 68 CNC kernel, the machine uses NUM Ethercat I/O terminals and a dual-processor Flexium FS152i operator panel with a 15" flat screen and hard drive. The custom human-machine interface was developed by NUM Taiwan and is designed to be intuitive and easy to use.

To keep up with consumers' demands of greater quality, ISO 9001-certified Black & Decker U.S. Power Tool Operations (Fayetteville, North Carolina) knew it needed to seek the best technology. Goals included quieter, smoother operation for the small electric motors inside power tools and tight tolerances for surface finish and roundness of shafts and spindles for the small, high-speed electric motors.

At the heart of all the tools is the motor shaft or spindle. Typically steel, these parts are usually shaped on a screw machine and ground to finish specifications. Some are ground from barstock. Most have multiple diameters.

Black & Decker engineers knew that upgrading grinding capability could have a big impact on plant production quality and cost. Warranty and rework issues are important dollar concerns, and plantwide Cpk goal is six sigma.

The solution was to purchase two Koyo CNC precision centerless grinders with automatic parts feeders and parts handling. Previously, multiple diameters on armature shafts had been ground on a manual, between-center grinding machine with contact gaging and cam-type dressers. Production rates sometimes lagged demand, and part quality could be inconsistent. As production increased and tolerances tightened, it became clear that a multi-axis CNC infeed grinder with CNC wheel dressing capability would be needed to help the plant keep up with the production requirements of several million parts a year.

Black & Decker engineers decided that a Koyo Model 6015 CNC in-feed centerless grinder with 6-inch wide grinding and regulating wheels with multiple diameters would help them meet the challenge. "It permitted faster setups and greater throughput, and the CNC dressing eliminated cam templates, saving time and improving grinding accuracy and reliability," said Mike Hinnant, manufacturing engineer. "Wheels are pre-dressed. And with the combination of CNC and pre-dressed wheels, we can quickly dedicate the machine to any shaft or spindle our plant requires as they need them."

"On one of the shafts we produce, we cut the cycle time from 28 seconds to 13 seconds," Mr. Hinnant continued. "The machine removes 0.010 inch of stock on diameter and maintains a 2.0 Cpk while maintaining roundness and surface roughness to part print tolerances." On that shaft, the machine grinds four diameters.

The Koyo centerless grinder is equipped with nine axes for machining, including two axes for grinding wheel dressing, two axes for regulating wheel dressing, two axes of infeed, upper and lower slide, two axes for loading and one axis for automatic swivel for taper control. It also includes several sets of grippers for automatic loading of eight different part numbers.

Black & Decker 's second machine was a Koyo KC-200 CNC in-feed centerless grinder. The main need was to be able to grind longer parts than would fit on the 6015 and to provide increased capacity. For its part in the production improvement at the plant, the KC-200 cut cycle times approximately in half for a family of nine parts it grinds.

Part quality is checked automatically with a non-contact post-process laser gage. Size and taper data is automatically fed back to the CNC, which compensates by adjusting the table and swivel axes.

"Roundness on the motor shafts is a critical specification," said Mr. Hinnant. "If the shaft is not round, the motor will arc and fail. We are minimizing lobing by optimizing regulating wheel speed, number of dresses on the wheel, and blade tungsten carbide inserts height." With CNC, hydraulics have no part on the KC-200, and thermal effects on machine function are avoided.

In operation, several hundred parts are loaded at one time through a hopper, freeing the operator to perform other tasks. Parts cycle through the machine automatically, followed by a blow-off and the laser gaging before being deposited into a bin.

Environmentally, the machine is clean, said Steve Terry, group leader on the shaft machining line. A mist collection system keeps the air around the machine clean and free of irritating vapors. And the part blow-off at the laser gaging station is so effective that not only is gaging reliable, but the usual post-process part-cleaning operation has been eliminated, saving 55 gallons of solvent a year, yet permitting a part storage life of up to 30 days, rust-free.

"All in all, the machines have been a very positive experience—with improved part quality, 50 percent greater productivity, and noticeable environmental improvement," Mr. Hinnant said.

The choice between a positive and a negative rake angle for a carbide insert depends on several factors, including the material being machined, the cutting conditions, and the desired outcomes. Here's a breakdown of when each type of rake angle might be more appropriate:Positive Rake Angle:A positive rake angle involves angling the cutting edge of the insert in a direction that points away from the workpiece. This configuration is generally suitable for softer materials and light cutting conditions. Here are some situations where a positive rake angle might be recommended:Soft Materials: Positive rake angles are effective for machining soft materials like aluminum, plastics, and non-ferrous metals. The sharp cutting edge engages the material more aggressively, minimizing the risk of built-up edge and improving chip evacuation.Low Cutting Forces: When the cutting forces are relatively low, a positive rake angle can help reduce cutting resistance and power consumption. This is important for prolonging tool life and achieving better surface finishes.High Speed Machining: In high-speed machining, a positive rake angle can help minimize heat generation at the cutting edge due to reduced friction between the tool and the workpiece.Negative Rake Angle:A negative rake angle involves angling the cutting edge in a direction that points towards the workpiece. This configuration is generally more suitable for tougher materials and heavy U Drill Inserts cutting conditions. Here are some situations where a negative rake angle might be more appropriate:Hard Materials: Negative rake angles are effective for machining hard materials like hardened steels, cast iron, and abrasive alloys. The stronger edge can withstand the higher cutting forces associated with these materials.Heavy Cutting: When performing heavy-duty machining operations, a negative rake angle provides better tool stability and can handle the higher forces and loads involved.High Accuracy and Surface Finish: Negative rake angles can contribute to better surface finish and dimensional accuracy, especially in applications where precision is crucial.Interrupted Cuts: When machining materials with irregularities, such as when encountering interruptions or varying hardness within a workpiece, a negative rake angle can provide Cemented Carbide Inserts better chip control and reduce the risk of chipping or breakage.In practical terms, the choice between positive and negative rake angles might not always be binary. There are also neutral rake angles that offer a balance between the two. Moreover, modern machining techniques and tool geometries have evolved to provide more versatile inserts that can handle a wider range of materials and cutting conditions without the need for frequent tool changes.Before making a decision, it's important to consider the specific characteristics of the material being machined, the machining parameters, the desired outcome (e.g., surface finish, tool life, productivity).

Only based on the full development of these technologies can high-speed cutting technology have true meaning.High-Speed Cutting Process: The processing technology is one of the key technologies for successful high-speed cutting. The high-speed cutting process technology includes the selection of cutting parameters, cutting paths, and the selection of tool tungsten carbide inserts materials, and tool geometric parameters.(1) Selection of Cutting Parameters This includes the direction of the tool approaching the workpiece, the angle of approach, the direction of movement, and the cutting process (up milling or down milling).(2) Selection and Optimization of Cutting Paths The optimization of cutting paths aims to improve the durability of the tool, improve cutting efficiency, obtain minimal machining deformation, improve machine tool utilization, and fully realize the advantages of high-speed cutting.(3) Selection of Tool Materials The reasonable selection of tool materials follows the following principles: 1. The mechanical properties of the cutting tool material should match those of the workpiece material, mainly referring to the mechanical properties of the strength, toughness, and hardness of the workpiece material.The hardness order of tool materials is: PCD > PCBN > Al2O3-based ceramics > Si3N4-based ceramics > TiC(N)-based hard alloys > WC-based ultra-fine grain hard alloys > high-speed steel (HSS). The bending strength order of tool materials is: high-speed steel (HSS) > WC-based ultra-fine grain hard alloys > TiC(N)-based hard alloys > Si3N4-based ceramics > Al2O3-based ceramics > PCD > PCBN. The order of magnitude of fracture toughness is:high-speed steel (HSS) > WC-based ultra-fine grain hard alloys > TiC(N)-based hard alloys > PCBN > PCD > Si3N4-based ceramics > Al2O3-based ceramics.Tools with excellent high-temperature mechanical properties are particularly suitable for high-speed cutting.

Designed for the Supermini tool system, Horn’s HP geometry is suitable for drilling, boring, face cemented carbide inserts turning and skimming. The addition of this geometry is said to make the Supermini into a multi-functional tool. The new cutting geometry is said to enable higher cutting parameters, including in-feed rates. When boring, the tool provides an accurate 90-degree shoulder at the base. The trailing cutting edge (wiper geometry) produces good surface quality, even at high feed rates, the company says.

In addition to turning operations, the tool can also be used for drilling into solid material in diameters ranging from 3 to 7 mm (0.118" to 0.276"). While the Supermini HP’s Carbide Turning Inserts performance data cannot compete with normal drills, the tool is intended to solve the problem of not having enough tool locations in the machine. The Supermini HP thus offers the option of immediately boring an inner contour after drilling, without needing to change the tool. With the single-edged version, various bore diameters can be produced using a single tool.

Horn provides tools for optimum chip control with and without a chipbreaker. For turning, the variant with a chipbreaker is recommended. The chipbreaker version is not used for drilling. The slightly twisted flute removes chips from the machining zone. The EG35 tool coating enables versatile machining of  both normal and stainless steels.
