PCD Calculator and Programming App


What is the VMC machine?

A VMC is a machine with a CNC (Computer Numerical Control) controller. As mentioned, the cutting head in this milling machine is vertical and is a particular type of milling machine where the spindle runs in a vertical axis known as the “z” axis. They are typically enclosed and most often used for cutting metal.

PCD calculator and programming application is a kind of application which helps new CNC/VMC Programmers to know the coordinates of a Pitch Circle Diameter/PCD holes.
It’s not an ordinary PCD Calculator, it’s most helpful application for creating VMC/CNC Program in few seconds.
It has following features:-
• Reliable to inform operator about PCD coordinates.
• Creating VMC machine program in few seconds.
• There are two different option to choose as your requirement.
• It is very easy to understand with the help of diagram of every required data related information.
• You can share generated program with anyone.
• You can also copy all generated program with the help of long press option.
• It’s work like CAM/Computer Aided Manufacturing.
• It’s safe & secure.
• Time saver.
• Accurate.
• Easy to use.
• Absolute free


Vertical machining center (VMC) refers to the machining center of which the spindle axis and the worktable set vertically, it can perform milling, boring, drilling, tapping, thread cutting, and more operations.

What is difference between CNC and VMC?

There is no difference between the two machines. VMC is a machine with CNC (Computer Numerical Control) controller. As mentioned, the cutting head in this milling machine is vertical and is a special type of milling machine in which the spindle moves in a vertical axis called the "z" axis.

How many types of VMC machines are there?


Four Types Of Five-Axis Machining Centers. Different machines offer different approaches to rotary travel, and each design has its own strengths. Here's how they compare.

What is HMC and VMC?

CNC machining centers describe a wide range of machine tools including CNC milling and drilling machines, which include vertical machining centers (VMC), horizontal machining centers (HMC) as well as 4th and 5th axis machines. Most include automatic tool changers from 20 to over 500 tools.

The Fundamentals of a Vertical Machining Center (VMC)

Introduction to Vertical Machining
Vertical Machining has been around in its most basic form for more than 150 years. Yet, it's still one of the newest forms of machining technology (turning/lathes is the oldest). The process of “milling” entails a rotating cutter, or drilling bit, and a movable work table, which the workpiece is affixed to.

The cutter is attached to and rotated in a housing called the "spindle." Through the sharpness of the tool and force of the table pushing the material into the cutter, the material yields and is cut or shaved away as desired. The axis of force can be up/down (referred to as the Z-Axis) left/right (referred to as the X-Axis), or front to back (referred to as the Y-Axis).

VMCs all use a commonality of components, which are as follows:

Rotating Spindle — The Spindle, which is perpendicular to the working surface or table, can hold a variety of cutting tools (or mills as they are sometimes called). The spindle cartridge is mounted in a housing that moved up and down—this direction of motion is called the Z-Axis.
Table — The Table is a platform on which to mount workpieces—either directly or through a variety of fixtures like milled aluminum plates or hard clamping vises. The table has a motion of left and right, which we call the X-Axis, and front to back, which is called the Y-Axis. These two axes of motion, coupled with the Z-Axis, allow for virtually unlimited contouring across the planes of motion.
