Machining a Complex Part with Harvey Tool

/0 Comments/in , , , , , , , , /by

Complex parts require more than a single operation. Features such as contours, chamfers, engraved details, and precision holes often demand multiple tooling strategies working together throughout the machining process.

In the video below, watch a single component progress from a block of Ti-6Al-4V to a finished part through more than 10 machining applications, each supported by specialized Harvey Tool solutions. 

Operations throughout the process utilize a range of tooling, including Variable Pitch End Mills for Titanium, Miniature Ball End Mills, Miniature Chamfer End Mills, High Performance Drills for Prehardened Steels, and Engraving Cutters.Each step demonstrates how selecting the right tool contributes to accuracy, surface finish, and overall part quality.

Explore the full range of solutions available in the 2026 Harvey Tool Catalog, featuring more than 31,000 miniature and specialty cutting tools designed to support even the most demanding applications.

Watch this great video from @go.manufacturing shared to @helicaltools Instagram, which features Helical’s 3 Flute 45° Helix Square End Mill for Aluminum in action.

“Sit back and enjoy the raw sights and sounds of a @helicaltools 1/4” endmill taking a .050” stepover cut through .900” of aluminum at 100 ipm. ✌️”

Designed for outstanding performance and accelerated material removal rates in aluminum and non-ferrous materials, this tool’s 45° high helix makes it ideal for finishing due to its high shear angle and cutting aggressiveness. In addition, the high helix and 3 flute design simultaneously create efficient chip evacuation and metal removal rates.

Helical x Mastercam: Continuous Time in Cut (CTIC)

/0 Comments/in , , , /by

Don Grandt, Harvey Performance Company National Application Engineer, met up with Jesse Trinque at the Mastercam Manufacturing Lab to demo some Helical Solutions End Mills and discuss Continuous Time In Cut (CTIC).

Continuous Time in Cut (CTIC) is the amount of time that a tool is engaged with a material. When an end mill is in a cut for too long, the friction can build and surface foot can be sacrificed, greatly affecting the performance and wear of a tool.

Check out this video to watch Jesse and Don test out how different levels of CTIC directly affect tool life and performance. This series of tests, which were facilitated by Mastercam, were conducted in Okuma’s GENOS M560-V, and utilized tool paths from Mastercam. For tooling, a standard ½” Helical Solutions HEV-6, a 6 flute, variable pitch end mill with a .03” corner radius, was used to machine 17-4 stainless steel.

All tests used the same cutting parameters, setup, material, and tool, with altered CTIC.

Take a Deeper Dive Into CTIC

Tune into this episode of In The Loupe TV to learn how you can manipulate Continuous Time In Cut (CTIC) and surface foot to reduce heat in your machining applications.

Check out the clean finish left by Helical Solutions’ 4 Flute Taper Form Multi-Axis Finishing Tool in this video collaboration done with @mastercam. 

Multi-Axis Finishers are Helical’s solution for operations with extremely high surface finish requirements. When switching from a traditional ball end mill, finish requirements can be dramatically improved, and cycle times can be cut down to a fraction of the time.

Designed to perfect your finishing operations, Helical’s Multi-Axis Finishers feature a specially defined profile with a large radius. This large radius allows for a greater stepover to be used pass-to-pass, while keeping the same cusp height as a ball end mill. Fully stocked in a variety of profiles and flute counts, these tools are offered for both Aluminum & Non-ferrous materials and Stainless Steels & High Temp Alloys.
