Centrifugal Iso-finishing for Additive Manufactured PartsDDaveDavidson
Centrifugal Iso-Finishing is a high-energy, high-quality, high-speed hands-free mechanical method for deburring, finishing and polishing of 3D printed (additive manufactured) parts as well as coventional subtractive manufactured parts. High Centrifugal force is utilized to accelerated process cycle times and make use of smaller dimensioned media to access intricate and complex part shapes. Useful for hand-deburring minimization and for developing low-micro-inch polished surfaces. Centrifugal Iso-Burnishing can be used for developing compressive stress in part surfaces on the order of that achieved by shot peening making parts much more resistant to fatigue failure or fracture. Plateaud or planarized surfaces improve bearing load capacity of cooperating parts with more wear resistance and improved tribological properties.

Mass media finishing techniques improve part performance and service life, and these processes can be tailored or modified to amplify this effect.

This facet of edge and surface finishing deserves closer scrutiny and this is also true of larger and more complex parts – only more so
INTRODUCTION: The Turbo-Finish process (also referred to as Turbo-Abrasive Machining )imparts beneficial compressive residual stress to edges and surfaces. and as all critical features of the part are processed simultaneously, it can produce a stress equilibrium throughout the entire part. One of the signature advantages of the process is that it is capable of producing peening like metal surface improvement effects, while simultaneously developing isotropic surfaces and deburring and edge-contouring sharp edged features This combination of edge and surface effects can help extend part life on components by mitigating crack propagation.

Turbo-Finish and premature fatigue failure prevention and life extension. Turbo-Finish’s unique ability to produce isotropic surfaces on rotating parts can make them much less susceptible to problems associated with crack propagation. Additionally, the elimination of stress risers, and the generation of round edges are used to help extend component life. Rotating parts can especially benefit from the Turbo-Finish process. Disks and other rotating parts can all benefit from this surface and edge conditioning. Highly finished surfaces also tend to pick up less residual contaminants from operations. and smooth isotropic surfaces generate less turbulent air flow across their surfaces. Additionally, the Turbo-Finish process imparts beneficial compressive residual stress. As critical features of the part are processed simultaneously, it can produce a stress equilibrium throughout the entire part. One of the signature advantages of the process is that it is capable of producing peening like metal surface improvement effects, while simultaneously developing isotropic surfaces and deburring and edge-contouring sharp edged features

Centrifugal Iso-Finishing Technical article as seen in Products Finishing mag...Dave Davidson
This high-speed, high-intensity mass finishing
method can improve part performance. Centrifugal iso-finishing can be used not only for deburring and edge-contour, but also to
develop surface finish attributes that improve the performance,
surface integrity and service life of components.
A High-Speed, High-Energy Alternative
Centrifugal iso-finishing is a high-speed and high-intensity
mass finishing method in which abrasive or polishing materials are caused to interact with part edges and surfaces
with 10 times the surface pressure of low-energy finishing
methods. What this means, in practical terms, is that it is
possible to produce very refined surface finishes in abbreviated process cycle times. It also means that parts with
complex and detailed geometries can be deburred with a
minimum of manual intervention.

It's the Finish that Counts. Technical Magazine article reprint.Dave Davidson
A conventionally produced surface (turned, milled,
ground, EDM) is typically Gaussian in nature, that is,
the peak and valley distribution is pretty much equal
in height. This type of surface can be very unstable and
unpredictable when wear and load bearing are considered. The images in Figure 1 demonstrate this type of
surface.
There are many ways to produce plateaued surfaces.
They are varied in approach but all have the ability to
control the surface peak characteristics separately for
the valley characteristics. Methods that are used to improve surfaces for performance and increased service life include centrifugal barrel finishing, turbo-abrasive machining (aka Turbo-Finish) and isotropic micro-finishing with vibratory finishing equipment.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Aero def 2017 high speed dry finishing of rotating hardware
1. PRESENTED BY
High-Speed Dry Spindle Deburring
and Finishing of Rotating Hardware
Dr. Michael Massarsky, President, Turbo-Finish Corporation
Dave Davidson, SME Deburring Technical Group,
2. Turbo-Abrasive
Machining and
Finishing
• Turbo-Abrasive Machining
(TAM) is a mechanical
deburring and finishing method
originally developed primarily
to automate edge finishing
procedures on complex
rationally oriented and
symmetrical aerospace engine
components
• Since its inception this method
of utilizing fluidized free
abrasive materials has
facilitated significant reductions
in the amount of manual
intervention required to deburr
large components by these
manufacturers
• Additionally, the process has
also proved to be useful in edge
and surface finishing a wide
variety of other non-rotational
components by in incorporating
these components into fixing
systems
6. Turbo-Abrasive Machining
(TAM) and Finishing
• Turbo-Finish is capable of running both rotating and
large volumes of smaller non-rotating parts in dry
spindle finish applications.
• (1) Dry operation. Turbo-Finish produces both
smoothing and polished surface effects with an entirely
dry operation. No wet waste is generated.
• (2) Horizontal Spindle Operation. Unlike other spindle
finish methods, the Turbo-Finish method utilizes
horizontal spindles, accommodating several parts or
part fixtures on the same spindle or on multiple
processing spindles.
• (3) Rapid edge and surface finish development.
Unlike other spindle-finish methods, spindle rotating
speeds in the hundreds and even thousands rpm are
possible because of Turbo-Finish’s unique media
delivery system.
• (4) Economical Tooling and Media. Much of the work-
holding tooling can be made from various plastic
materials and still maintain extended service life.
7. Industry Segment Examples
• INDUSTRIES:
• Aerospace Industry
• turbine and compressor discs
• turbine blades
• turbine impellers
• turbine blisks
• gears for wind power turbines
• (up to 40” in diameter)
• Cutting tools
• taps
• drills
• hobs
• milling cutters
Power generation Industry
Turbine discs
(up to 46” in diameter)

8. TAM BASICS
• Fluidized bed technology develops
complete envelopment of parts
with free abrasive media
• Rotational movement of parts
produces high intensity abrasive
particle contact with part edges
and surfaces to develop edge
contour and surface finish
• Relatively small media and high
speed rotation promote processing
of intricate or complex geometries
and even simple interior channels
• A wide variety of abrasive and
polishing media can be utilized
from heavy abrasives to polishing
media for developing low micro-
inch surfaces
9. SIGNIFICANT PROCESS
CHARACTERISTICS
• Rapid machine cycles replace tedious
manual processes
• Intricate part geometries accessed
(small media – high intensity rolling or
glancing contact)
• Completely DRY abrasive, polishing or
non- abrasive operation, NO WET
WASTE DISPOSAL
• Micro-textured surfaces are excellent
substrate for coatings
• Metal surface improvement,
compressive stress effects, enhanced
metal fatigue resistance
• No part-on-part contact or impingement
10. Significant Process
Characteristics
• HORIZONTAL SPINDLE
OPERATION
• Multiple parts can be fixtured on
a single spindle
• Unique abrasive delivery system
(fluidized bed) assures uniform
processing of all parts on the
spindle
• The abrasive fluidized bed
permits high-speed rotational
operation. Speeds of 800- 2000
rpm are commonly specified
• The takt time (floor-to-floor) for
running these disks was
calculated to be 60 seconds
11. Small diameter
complex parts
• Smaller diameter parts can
also be run in multiple
spindle equipment
• These rotor parts were run
in a dry abrasive process in
an eight spindle machine
• Takt time per part (floor to
floor) was less than sixty
seconds
12. Dry Abrasive and
Polishing Media
Materials
• Abrasive Material such as Aluminum Oxide,
Zirconium Oxide
• Polishing and Micro-Finishing media such as
soft granulates to develop lower micro-inch
surfaces and develop refined reflective
surfaces to assist visual inspection
• Surface roughness pattern orientation to
vector
• Abrasive particle size can vary
• Abrasive composition can vary
• Multiple processes on the same part can
used successively finer abrasive materials to
achieve very fine edge and surface finishes
when required
14. Dry Micro-
Finishing
• [Ra = 11.8 micro-inch]
• Surface and edge
finish effects can be
further improved
when multiple turbo-
abrasive machining
steps utilizing
sequentially finer
abrasive materials.
• This disc photo and
graph shows surfaces
after two sequential
TAM cycles.
18. Extreme

25. Dry High-
Speed Gear
Deburring
• After TAM processing
• Burrs Removed
• Sharp edge condition
replaced with contour
• Manual deburring
eliminated
• Reject/rework rates
reduced close to zero
• Isotropic surface
development
26. Automated Disk
Finishing
• Several advantages when
compared with other mechanical
finishing technologies
• Automation and mechanization of
deburring for complex rotating
parts. Edge contour, surface-
finishing improvement and
compressive stresses developed
on parts SIMULTANEOUSLY
• Manual process consuming many
hours are reduced to automated
machining cycles of only a few
minutes
• High flow of dry abrasive particles
allows penetration of an abrasive
action on many difficult to access
part areas
• Low energy consumption (unlike
blasting, peening or other
pressure or impact processes)
• Low consumable cost. The current
track record indicates that
abrasive costs per disk are
approximately $0.15 per disk for
10 inch disks, and $0.50 for 20
inch disks
27. TAM Features and Benefits
• The TF technology, in addition to producing a good radius
on the feature can create an isotropic surface effect. The
isotropic surface effect minimizes potential crack
propagation points and improves stress equilibrium
among part features. All common machining and manual
finishing methods produce non isotropic but linear
characteristics. This contributes to tension concentration
of the sharp surface peaks and easier crack propagation
• The microimpact of abrasive small particles and a high
velocity of the part produce beneficial compressive
stresses and also improve the surface integrity and fatigue
resistance of many types of critical components
• As TF is a cold process, it causes no structural phase
transformation on the surface. The TF technology
increases the service life from 30% to 100%, depending of
the part material (nickel alloy, stainless steel, titanium
