2008 Numbers2008 Numbers• At the peak of the economy

Haas posted some impressive production numbers.

• At the highest point we were manufacturing over 1300 machines per month!

• Right now we are setting ourselves up to achieve even better numbers more efficiently.

88

How do we do itHow do we do it

?? • In order to support customer demands, the

shop must use the most advanced technology, and our Haas culture to produce the parts needed to build our entire product lines

• Technology• Culture

How Do We Do It?How Do We Do It?

• The “Haas Culture” is the underlying force that has brought us to where we are today.

• All Haas employees embrace that culture and work together to keep it strong and evolving positively.

1010

How Do We Do It?How Do We Do It?

• Positive characteristics to our culture:– We are driven to succeed. – We are professional in our

conduct.– We measure our results.– We think globally.– We act locally.

SpillsSpills

• If a spill occurs, do the following:– Contain it – use absorbent socks or red

rags.– Clean it – use degreaser and soapy

water to clean the spill.-Yellow spill kits can be found in every

building with the correct tools to clean up a spill.

• If a spill cannot be cleaned up immediately, set up a barrier and notify security at ext. 8688.

ConclusionConclusion

Always remember:

• Workplace safety starts with YOU!

• Safety is a priority at Haas Automation.

• Be aware of safety for yourself and your co-workers.

• Immediately report any unsafe acts or conditions to a supervisor or manager.

• Master schedule is determined by the company’s forecast

• The schedule projects our goals for the month and year.

• It drives what parts need to be made and what machines will be built

Material MovementMaterial Movement

• Ask yourself: “Where is the next place?”• Outside process?• Next machining operation?• Deburr?• Inventory?• Assembly?

– You should use a move sheet – (unless you are moving casting)

6060

• Proper packing reduces cost and damage to critical parts

• It all begins with YOU! • More detailed

information is presented in the Material Movement class!


Move sheet

6161

• Use this Not this

• The reason Haas bought these part specific containers was to prevent damage of critical precision parts

No separators

• Preventing critical parts from being damaged will benefit the company as a whole by reducing costs and ultimately improving our bottom line

Something you should ask for Something you should ask for every part you machine! every part you machine!

A turning point; crucial or decisive:

a critical point in the campaign. Indispensable; essential: a critical element of the plan;

a second income that is critical to the family's well-

being.

8181


In our case critical means that parts and/or features are

necessary for proper assembly and function of a Haas machine

Critical-Mating FeaturesCritical-Mating Features

• Critical features will be different for every part, but it has to do with how the mating parts assemble together.

• They are the physical, functional, and performance characteristics that uniquely identify a component.

Remember:

FORM, FIT, AND FUNCTION!

DisassemblyDisassembly

• Time and money could have been saved by not having to disassemble to find out why the machine will not function properly

9191

Know What is CriticalKnow What is Critical

• Always go to Assembly to see where your parts are used. Ask: “What is critical?”

• Whether running complex or simple parts, the first question to ask is “What is critical?”

• Your help is necessary to prevent unusable parts and wasted time

9292

Critical !!!Critical !!!• In this

example the size of the diameter must be held to +.002 / -.000 and perpendicular to the bottom within .0005 to ensure proper functionality

NOTE: Perpendicular means that the mounting face must be

square (90 degrees) to the bottom

determine what fixture and/or parts are loaded.

• Eliminate inspection steps by using the machine to inspect features.

• Reduce chance of crash since there is less human interaction.

size and production is amazing!

125125

ConclusionConclusion• Safety is a

priority at Haas

126126

ConclusionConclusion• Work “flows” both

internally in the shop and also through the other departments like purchasing, inventory, assembly, and shipping

127127

ConclusionConclusion• Parts like 20-7016c

start as a blank bar before moving through the shop, then end up as part of a finished machine in assembly.

• We have well-defined processes!

128128

• Critical parts are checked to ensure proper functionality.

Know what is critical!


129129

ConclusionConclusion• Be aware: what you

do in your area has an effect on the next area “downstream”.

• You can help catch little problems before they grow into big problems

• You can help catch little problems before they grow into big problems

CHECK YOUR PARTS!

139139

Question 4Question 4• What is a mating surface and why are they

important?

• Mating surfaces are where 2 parts join together. They are important because if the surfaces are damaged the assembled parts may not pass a quality check.

140140

Question 5Question 5• What determines how you should check

dimensions?

Blueprint tolerances

• General rule of thumb- measuring tool should be 10x more accurate than the tolerance you are checking

141141

Question 6Question 6• What is the most basic thing to remember

with safety?

1. Common sense shall prevail!

2. Avoid hazardous situations and minimize risk

Use Your Head!

142142

Question 7Question 7• Why is it important to keep fixtures in good

condition?

• Parts that are not clamped securely can be dangerous, and can also cause quality problems.

Regular maintenance should not be ignored

143143

Question 8Question 8• Who are your

customers?

• How can you make sure your customers are satisfied with what you provide them?
