What is CNC?

CNC stands for Computer Numerical Control.

CNC machines allow motion control in a revolutionary manner. All forms of CNC equipment have two or more directions of motion, called axes. These axes can be precisely and automatically positioned along their lengths of travel. The two most common axis types are linear (driven along a straight path) and rotary (driven along a circular path). Instead of causing motion by turning cranks and handwheels as is required on conventional machine tools, CNC machines allow motions to be commanded through programmed commands.

What are the benefits of CNC?

Benefits include fewer mistakes caused by human error, consistent and predictable machining time for each workpiece. Today's CNC machines boast almost unbelievable accuracy and repeatability specifications. This means that once a program is verified, two, ten, or ten thousand identical workpieces can be easily produced with precision and consistency.

Why do costs vary with quantity?

One variable of costing is set-up time. This variable represents the time required to set up a machine to fabricate a part. As this is a fixed cost (does not vary with quantity of parts), its effect on the per-piece price varies with the quantity. For example, a one piece price is virtually entirely set up with little run time. On the other hand a 10,000 piece price consists mainly of run-time costing once a program is verified.

What if I know what I want but I don't know what material to make it out of?

PDA Engineering's emphasis on component manufacturing enables us to recognise the requirement and produce a well-designed part. We are always available to discuss material choices based on the customer's particular design requirements.
