Class Vocabulary

Vocabulary TermDefinition
[MSR UNIT OFF] A menu key that halts the use of the tool setter.
[MSR UNIT ON] A menu key that initiates the use of the tool setter.
actual diameter The real diameter of a tool as indicated during tool measurement. The actual diameter of a tool often differs from its nominal diameter.
calibration The process of tool setting during which all information related to a tool is established in the Mazak control.
constant wear compensation Fields in the tool data display that allow you to reduce part measurement errors due to swarf. Constant wear compensation is used when programming part probing measurement during machining.
cut direction A field in the tool data display that shows the rotational direction of the spindle and the directional orientation of the tool.
display select key A key on the lower left of the Matrix display that toggles between available displays and their particular menu keys. The display select key is sometimes called the chapter left key.
easy wear compensation Fields in the tool data display that allow you to account for wear in a predictable machining situation. Once a set number of parts has been reached, data in the EASY COMP fields is added to the WEAR COMP fields.
geometry offset An offset used on a lathe to account for the physical shape of a specific tool. Each tool requires its own geometry offset, which accounts for its length and width.
job sheet A document that includes all manufacturing specifications for a batch of parts.
left-hand tool A tool with a tip that, when laid flat on a table, points to the right.
list input display A screen on the right side of the tool data display that shows TOOL SET X and TOOL SET Z details.
lot The number of similar parts made with a particular tooling setup.
machine zero The origin of the machine coordinate system located above the lathe spindle and to the far upper right-hand corner of the lathe work area. The unchangeable machine zero point is located at the center of the turret and is also known as the home position.
maximum tool wear Fields in the tool data display that allow you to set a maximum allowable amount of wear compensation in each axis.
nominal diameter The stated diameter of a tool as intended during the tool's manufacture. Often, a tool's actual diameter differs from its nominal diameter.
nose radius compensation The process of slightly shifting the toolpath for the rounded tip of an insert during contouring, chamfering, and other multi-axis operations. Without nose radius compensation, many processes would yield inaccurate parts.
offset A numerical value stored in the CNC control that repositions machine components. Offsets are used to adjust for differences in tool geometry, part size, tool wear, etc.
qualified tool Also called a referenced tool, a tool that has been properly measured and setup. A qualified tool is one whose dimensions are known to the control.
radius offset An offset used on the lathe that slightly adjusts the tool to compensate for the rounded tip of an insert during contouring, chamfering, and other multi-axis operations.
reference workpiece zero point A point on the centerline in the Z-axis from which the Z-offset is measured. The reference workpiece zero point is located 10 cm off the face of the chuck.
referenced tool Also called a qualified tool, a tool that has been properly measured and setup. A referenced tool is one whose dimensions are known to the control.
right-hand tool A tool with a tip that, when laid flat on a table, points to the left.
rotational direction A tool data specification that accounts for the direction of the turning spindle. The rotational direction is indicated by a curved arrow.
teach function A feature of the Mazak control that allows you to automatically enter measured values into a particular register.
tolerance An unwanted but acceptable deviation from a given dimension. Tolerances indicate the allowable difference between a physical feature and its intended design.
tool cutting angle A field in the tool data display that allows you to compensate for the angle of the tool in relation to the workpiece surface. Most cutting angles are either 90°, 93°, and 95°.
tool data display The area of the Matrix control where tool-related information is managed. The tool data display contains information related to tool offsets.
tool data menu key A menu key that accesses the tool data display.
tool measure menu key A soft key that appears at the bottom of the tool data display and initiates the tool setting process.
tool measuring unit A Mazatrol programming unit that allows you to program the automatic recalibration of a specified tool during program execution. The tool measuring unit can be used to account for wear.
Tool Mes function A feature of the Mazak control that allows you to establish tool offset information using a tool setter.
tool nose angle A field in the tool data display that allows you to compensate for the actual angle of the tool tip. Common edge angles include 35°, 55°, and 80° on a diamond-shaped insert.
tool nose radius A field in the tool data display that allows you to compensate for the rounded nose that exists on the end of most turning tools.
tool number A number that indicates the location on the turret where the tool resides. Every tool in the turret has a tool number, which helps organize tool data.
tool offset An offset used on a lathe to account for the physical shape of a specific tool. Tool offsets include geometry offsets, radius offsets, and tool orientation offsets.
tool orientation A tool data specification that accounts for the way the tool is mounted in the turret. Orientations include right-handed (RG) and left-handed (LF).
tool orientation offset An offset that defines which direction the tool tip is facing in relation to the machine axes.
TOOL SET X The distance in the X-axis from the tool nose to the reference workpiece zero point.
TOOL SET Z The distance in the Z-axis from the tool nose to the reference workpiece zero point.
tool setter An accessory that allows the automatic measurement of tool-related offsets.
tool setting The process of touching a tool to a tool setter, during which all information related to a tool is established in the Mazak control. Tool setting is also sometimes called calibration.
tool wear compensation Fields in the tool data display that allow you to make slight adjustments to the registered tool dimensional data in each axis.
wear offset An offset that allows for the slight adjustment of the tool location. Wear offsets account for part deflection, tool wear, etc.
work offset An offset used to positon the turret in reference to the reference workpiece zero point and program zero. A work offset in Mazatrol is also known as the Z-offset.
workpiece zero The origin of both the workpiece coordinates system and the part program for a particular workpiece. Workpiece zero, commonly called program zero, is unique to each workpiece design and is selected by a part programmer.
Z-offset A work offset that is the difference between the reference workpiece zero point and the program zero location on the face of a part.
