Question 1

Loading tools through the spindle is very useful for setting what compensation values?

Answer 1

Tool length compensation

Question 2

Loading tools through the spindle requires you activate the automatic tool changer in what mode?

Answer 2

Manual data input, MDI

Question 3

What is the normal tool change position for a vertical Machining Center?

Answer 3

Z axis zero return

Question 4

Name four things that are required before an automatic tool changer can change tools.

Answer 4

Load assembled tools into magazine

Position machine axes to the tool change position, Z zero return

Provide a command to make tool change, T word and M06

Provide command that rotates the magazine to bring next toolstation to ready position, T word

Question 5

Why is the double arm automatic tool changer the most efficient?

Answer 5

It gets the next tool station to the ready position while Machining occurs

Question 6

What tool changer styles do not use a change arm?

Answer 6

Rotary and table mounted

Question 7

When is tool length compensation in stated?

Answer 7

During each tools first Z-axis approach to the workpiece

Question 8

What codes are used to initiate tool length compensation?

Answer 8

G43 and an H word

Question 9

Describe two popular ways to use tool length compensation?

Answer 9

The tool length is placed in the tool length compensation offset register

The distance from the cutting tool tip to The z axis program zero point is placed in the tool length compensation offset register

Question 10

Name three reasons why method #1 is recommended when setting tool length compensation

Answer 10

You can measure tool length compensation values offline using a tool length measuring device

You don’t have to re-measure cutting tools

Share cutting tools among Machining centres

Question 11

When using an offline tool length measuring machine will the value be positive or negative?

Answer 11

Negative

Question 12

If you make the tool length compensation value the length of the cutting tool, what value must you place in the Z axis register of the fixture offset (G54)?

Answer 12

The distance from the spindle nose or (gauge line AIT), to program zero point

Question 13

If you make the tool length compensation value the distance from the tool tip to program zero, what value must you place in the Z axis register of the program zero assignment value?

Answer 13

Zero

Question 14

List three different names for part zero

Answer 14

Program zero point, work zero, workpiece origin

Question 15

What is part zero purpose in X and Y?

Answer 15

It involves determining the distance in each axis from the zero return position to the program zero point
