End Mills Increases Metal Removal Rates, Tool Life

Seco Tools’ Jabro JHF180 MEGA-64 solid carbide end mill series is suited for machining hardened steels ranging from 48 to 62 HRC. The end mill features a rigid 0.9-degree tapered neck design that reduces tool deflection, enables deep cavity milling and improves surface finish, the company says. The flute cavity design and angle on the back of the tooth guide and eject the chips away from the cutting TCGT Insert edge. It also features a wear-resistant MEGA-64 AlTiN coating with an 8-percent carbide substrate.

The end mill is available in diameters ranging from 2 to 16 mm with reach options ranging from 2× to 7× diameter. It is equipped with three, four or five flutes, depending on the style. The end mill range is suited for high-feed milling applications, including face milling, slotting, ramping, helical interpolation, ramping and Z-level machining.

The company’s high-feed milling strategy is based on transferring cutting forces from the radial direction to axial, which reduces the risk for vibrations and stabilizes machining. Small depths of cut combined with high table feeds produce a thinner chip that carries heat away from the cutting edge and reduces cutting forces, the company says. This approach reduces heat generation to Cutting Tool Inserts extend tool life and increases the metal removal rate.

A Custom Macro For Tool Change Format

Much of CNC manual programming is redundant. Similar commands must be repeated on a fairly regular basis, especially when tool changes must be made. Because these commands are only similar (not identical), subprograms will not help when it comes to minimizing them. But if your control has custom macro B (or any version of parametric programming), you can simplify the commands required for tool changing.

Even if you program with a computer aided manufacturing (CAM) system, you must consider how difficult it is for operators to run your programs. The techniques we show will simplify programming (especially for manual programmers), ensure consistency for tool changing commands, make your programs more fail-safe and make it easier for setup people and operators to rerun tools.

First, consider a typical series of commands that are needed when you make a tool change on a vertical machining center. Of course, the specific commands for your particular machine(s) will vary. Similar commands will be required for turning centers (or any multi-tool CNC machine tool).

N060 M09 (Turn off coolant)

N065 G91 G28 Z0 M19 (return to tool change position, orient spindle)

N070 T02 M06 (Place desired tool in spindle)

N075 G90 G54 S500 M03 T03 (Select absolute mode, fixture offset, start spindle and select next tool)N080 G00 X1.5 Y2.0 (Rapid to first X and Y position)N085 G43 H02 Z0.1 (Instate tool length compensation, rapid to first Z position)N090 M08 (Start coolant)

Note that the structure of these commands will remain the same for every tool change you make. Only the values of the numbers in bold italics will change from tool change to tool change. Again, these commands are redundant and tedious to write. It’s easy for manual programmers to forget key words or commands. Consider this custom macro call statement that can be used to invoke a special tool change custom macro.

N060 G65 P1000 T02 S500 X1.5 Y2.0 Z0.1 (Make tool change)

When the custom macro (O1000) is executed, it will cause the machine to do everything done in the previous series of tool change commands. In our call statement, T represents the tool to be placed in the spindle. Our macro will assume that the tool to be used after this one follows in sequence (tool three in this case). If it does not, a W word (for waiting station) can be included in this command to specify which tool is coming up next in the program. We’ve left W out, so we’re letting the custom macro assume that the next tool will be station three. S specifies the spindle speed, and X, Y and Z specify the tool’s first approach position.

Here is the simple custom macro.

O1000 (Tool change custom macro)

IF [#23 NE #0] GOTO 1 (If W is included in call, skip default)

#23=#20 +1 (Set next waiting station tool to next number in sequence)

N1 M09 (Turn off coolant)

G91 G28 Z0 M19 (Return to tool change position, orient spindle)

T#20 M06 (Place desired tool in spindle)

G90 G54 S#19 M03 T#23 (Select absolute mode, fixture offset, start spindle and select next tool)

G00 X#24 Y#25 (Rapid to first X and Y position)

G43 H#20 Z#26 (Instate tool length compensation, rapid to first Z position)

M08 (Start coolant)

M99 (End of custom macro)

We’ve taken the set of tool change commands and replaced those hard-and-fixed values that change from tool change to tool change with local variables (T is represented by #20, W by #23, S by #19, X by #24, Y by #25 and Z by #26). We have also set a default value for W (#23) if it’s left out of the call statement. Look at the first two commands of the custom macro. If W is left out of the call statement (as it is in our example), the result of the IF statement will be false (W is vacant), and the next command (the default setting command) will be executed. #23 will be set to a value of whatever T (#20) is plus 1. If W is included in the call statement, #23 will have a value (#23 will not be vacant), the IF statement will be true and the default setting command will be skipped.

Though our example custom macro doesn’Surface Milling Inserts t show it, you could also include words and commands in the tool change format custom macro to make your programs more fail-safe. For example, you could include G80 and G40 in line N1 (when the coolant is turned off) to ensure that canned cycles and cutter radius compensation have been canceled. Most manual programmers will not do this, because they assume they’ve programmed correctly. Right after the tool change command (M06), you could include some safety commands to confirm that certain modes are still in their initialized states. Consider these commands.

G17 G20 G40 (Set XY plane, inch mode, cancel cutter radius compensation)G64 G69 G50.1 (Set normal cutting mode, cancel rotation, cancel mirror image)G80 G94 (Cancel canned cycle, select feed per minute mode)tungsten carbide inserts

Again, these commands can be placed in the custom macro right after the tool change and will ensure that the machine is in appropriate states. This is most important for the first tool the first time the program is run.

What about rerunning tools? One important task that CNC setup people and operators must perform on a regular basis is rerun tools. Our tool change format custom macro still allows rerunning tools. Actually, it will simplify the task. The restart block for rerunning tools is simply the call statement (G65 command) for each tool change. Everything required for restarting tools, including a movement to the appropriate tool change position, is included in the custom macro.

Also, if your setup people and operators are currently restarting tools by scanning to the T word, they have to scan twice (assuming you have a machine with a double arm tool changer). The first time they scan, they find the command in which the tool is being placed in the waiting station. The second time, they find where it is actually being placed in the spindle. With the tool change custom macro, only one scan is required.

Tool Lifetime Management Software Supports Multi Functional Tools

TDM Systems has released version 4.8 of its TDM software designed to optimize tool lifecycle management (TLM) as part of Industry 4.0 and Industrial Internet of Things initiatives. Version 4.8 includes a number of enhancements for multi-tool support, data import, wireless barcode scanner connection, and the ability to more easily and quickly generate solid models for tool assemblies, the company says.

This version of the software includes multi-tool data records that combine tool assembly data with a bill of materials to accommodate multi-functional tools with cutting edges for different machining purposes. Each respective cutting edge is assigned and linked as a single data record within the multi-tool record. When searching for tools, users can now see the search criteria corresponding to Lathe Inserts partial records as well as the full multi-tool data record.

Tool data can be imported from the MachiningCloud Internet-based tool database. This feature automatically assigns the ISO tool parameters from MachiningCloud to the TDM class/group structure parameters. A new menu tab in the tool assembly management shows the CAM programmer the required tool parameters. Depending on the CAM tool class, the programmer sees the associated TDM tool class with the relative graphic parameters and TDM parameter description.

Existing features have also been enhanced. Available since version 4.6, the Revolve Generator for generating 3D models from contours of rotationally symmetric items now works at the tool assembly level. The interface to the Casio DT-200 scanner has been extended in version 4.8 so that it can be connected to the system wirelessly. All issuing processes are made without caching, and offline transmissions via a base station are transmitted Cemented Carbide Inserts quickly to the system.

Engineering The Toolholder Assembly Process

Job shops are famously resourceful. To solve difficult machining problems or make work easier, they often invent their own solutions. Then they realize they might have a product to sell to other machine shops. That is how the Versa-LOK came about. The device, shown at left, is designed to make it easier and safer to put toolholders, collets and cutting tools together. It’s an alternative to using other methods that can damage the toolholder or invite unsafe use of hand tools.

This device was developed by David Lelonek’s company, Automated Machine Technologies, Inc. (AMT), in Orchard Park, New York. The company started out as a contract engineering and manufacturing service company. As this business grew, so did the company’s machining. Assembling cutters, collets and V-flange toolholders became a bottleneck, so Mr. Lelonek had one of his engineers design and build a fixture that worked better and was more versatile than devices currently available. This prototype was functional but not very attractive in CNMG Insert appearance. Recently, Mr. Lelonek decided to refine the operation and looks of the toolholder assembly fixture and produce it for the general market.

As pictured here, a spring-loaded lock collar that slides downward allows the toolholder to be inserted, while a guide sleeve inside prevents damage to the taper or flange. Releasing the lock collar engages the clamping mechanism automatically.

The rotating design allows the toolholder to be positioned in any one of eight 45-degree indexing steps for 360-degree total rotation. Pulling and the release a knob at the stub end of the fixture governs rotating freedom. To access the retention stud, for example, the holder can be turned 180 degrees. Various positioning angles allow wrenches and other tools to be applied properly and comfortably whether the user is right- or left-handed.slot milling cutters

The device is available currently for Cat-40 tapered toolholders but models for BT, HSK and VDI style toolholders are in development.

An awareness of lean manufacturing principles has made shops more conscious of the need to streamline tool assembly procedures. At the same time, special care of toolholders and cutters has become more urgent because these assets are rising in cost and their performance is often critical in increasingly precise operations. In light of these trends, devices that protect these assets and avoid wasted activity take on double value.
