Basic Machining Practice
The Key To Proper CNC Machine Usage!
You must understand basic machining practice as it relates to turning centers
20Though basic machining practice is beyond the scope of this course…
…you must understand:Machining operations
Rough turning/finish turningRough boring/finish boringDrillingTappingThreadingGrooving/neckingKnurling
Like:
21Though basic machining practice is beyond the scope of this course…
…you must understand:Machining operationsProcessing
Development of the machining order by which the workpiece is produced
Processing:
22Though basic machining practice is beyond the scope of this course…
…you must understand:Machining operationsProcessing
You must be able to determine spindle speed, feedrate, and depth of cut based
upon cutting tool material workpiece material, and rigidity of setup
Cutting conditions
23Though basic machining practice is beyond the scope of this course…
…you must understand:Machining operationsProcessing
You must be able to design safe work-holding setups
Cutting conditionsWork-holding setups
24Though basic machining practice is beyond the scope of this course…
…you must understand:Machining operationsProcessing
You must understand all aspects of basic machining practice in order to write safe, workable CNC programs
Cutting conditionsWork-holding setupsBlueprint reading, dimensioning, etc.

Machine Configurations
Turning centers are available in several styles
27There are many forms of CNC turning centers…
Universal slant bed Chucker slant bed Twin spindle horizontal Single spindle vertical Twin spindle vertical Mill/turn machines Gang type Sliding headstock
In all cases…X will be the diameter controlling axisZ will be the length controlling axis

X is DIAMETER
Once again:X is always the diameter-controlling axisZ is always the length controlling axis
Also:X+: always gets bigger in diameterZ+: always away from the spindle
Though some machine tool builders reverse the polarity of the X axis
