The

 

stock

 

may

 

not

 

be 

located

 

in

 

the

 

same

 

position 

relative

 

to

 

the

 

origin

 

point 

that

 

it

 

was

 

in

 

the

 

CAM 

software

 

used

 

to

 

create

 

the 

toolpaths 

 

2. Check

 

if

 

the

 

coordinate 

system

 

of

 

your

 

machining 

setup

 

in

 

CAM

 

is

 

set

 

up

 

so 

that

 

the

 

positive

 

Z

 

axis 

points

 

at

 

the

 

spindle

 

of

 

the 

Pocket

 

NC,

 

the

 

positive

 

axis

 

points

 

at

 

the

 

A

 

table, 

and

 

the

 

positive

 

Y

 

axis 

points

 

straight

 

up

 

from

 

the 

B

 

table.  

 

3. Check

 

if

 

the

 

toolpath

 

origin 

is

 

also

 

the

 

B

 

table 

offset/machine

 

origin

 

point 

and

 

that

 

the

 

toolpath 

coordinate

 

system

 

is 

appropriate.

 

Remember 

that

 

the

 

Z

 

axis

 

is

 

always

 

the 

Pocket

 

NC

 

spindle. 

 

4. Make

 

sure

 

that

 

your

 

stock 

is

 

located

 

in

 

the

 

same

 

place 

on

 

your

 

machine

 

as

 

it

 

was 

relative

 

to

 

the

 

origin

 

point

 

in 

your

 

CAM

 

program. 

 

The

 

drive/lead

 

screws 

squeak.  

The

 

end

 

of

 

the

 

lead

 

screw

 

is 

touching

 

the

 

frame

 

of

 

the 

machine

 

when

 

it

 

turns.   

1. Make

 

sure

 

that

 

the

 

screw 

and

 

the

 

hole

 

are

 

free

 

of 

debris.  

2. If

 

the

 

noise

 

it

 

minor

 

is

 

is 

best

 

to

 

let

 

it

 

wear

 

into 

position.

 

The

 

noise

 

should 

decrease

 

with

 

time 

-

Use

 

a

 

very

 

small

 

amount

 

of 

general

 

purpose

 

synthetic 

grease

 

to

 

lubricate

 

the

 

tip

 

of 

the

 

screw.  

-

Do

 

not

 

grease

 

the

 

whole 

screw.  

-

Do

 

not

 

put

 

grease

 

where

 

it 

will

 

contact

 

the 

anti-backlash

 

nuts.  

-

Grease

 

will

 

collect

 

debris 

and

 

may

 

cause

 

increased 

wear

 

on

 

your

 

machine.
