Machining Parameters
Feed, speed, load, and removal behavior.
Acceleration
Rate of change of axis velocity.
Axial Engagement
Amount of axial tool engagement into the workpiece (often equivalent to depth of cut).
Chip Thickness
Chip thickness in the cutting direction.
Chip Width
Chip dimension in the width-of-cut direction.
Constant RPM
Spindle control mode that maintains fixed rotational speed.
Constant Surface Speed (CSS)
Spindle control mode that maintains constant surface speed.
Cutting Force
Resultant force acting on the tool during cutting.
Cutting Power
Power required to perform cutting.
Cutting Ratio
Ratio of chip thickness to uncut chip thickness.
Cutting Speed
Surface speed at the contact point between tool edge and workpiece.
Cutting Temperature
Temperature generated in the cutting zone.
Depth of Cut (ap)
Axial depth of cut.
Feed Hold (Spindle On)
State that pauses feed while spindle rotation is maintained.
Feed per Revolution
Feed distance per spindle revolution.
Feed per Tooth
Advance distance per tooth per revolution.
Feed Rate
The speed at which a cutting tool advances along the workpiece in CNC machining, typically measured in mm/min (millimeters per minute) or IPM (inches per minute).
Feedrate Override
Proportional adjustment of current feedrate.
Finishing Allowance
Material thickness reserved for final finishing.
Jerk
Rate of change of acceleration (affects motion smoothness).
Material Removal Rate
Volume of material removed per unit time.
Radial Engagement
Amount of radial tool engagement into the workpiece (often equivalent to width of cut).
Rapid Traverse Rate
Axis movement speed during rapid traverse.
Roughing Allowance
Material allowance reserved during rough machining.
Spindle Override
Proportional adjustment of current spindle speed.
Spindle Speed
The rotational speed of the machine spindle, measured in RPM (revolutions per minute). It determines how fast the cutting tool or workpiece rotates during machining.
Spindle Torque
Magnitude of spindle output torque.
Stock Allowance
Amount of material reserved for subsequent machining.
Surface Speed
Linear speed at the contact point in circular motion.
Tool Load
Monitored value of actual tool or spindle load.
True Position
Geometric tolerance that controls feature location relative to datums.
Width of Cut (ae)
Radial width of cut.
