Abstract

There is provided a method and apparatus for reproducing the human head in three dimensional form by use of multiple material removal devices. The apparatus may include a platform for locating a blank with multiple material removing devices arranged around the centre of the platform. The material removing devices may be operated independently of one another to perform on the blank. The platform may be rotatable.

Description

Multiple material removal device.
This invention relates to a machine with multiple material removing devices.
It is known from GB 2377506 3-D Element Sculptor the removal of material from an oversize blank by a single element, with the time restriction this has where there are some 256 steps and each step covering a approximate distance of 300mm for a full size head at a velocity of 30mm per second indicating 42.6 minute to complete a cycle, this being to slow for mass producing individuality purposes.
The invention is a method and apparatus for reproducing the human head in the three dimensions form by use of multiple material removal devices. Which could take the form of a platform where there are multiple removing devices arranged around the centre of the machine and can be operated independently to perform on the blank. The blank being supported on a rotating device in the centre and the removing devices stationed at equal spacing's about the centre of the machine.
The material removing devices could be of two, three or four and even further multiples, where there are two they would be set opposite each other at 180 degrees, where there are three each device could be set at 120 degrees apart, where there are four they would be set at 90 degrees that is at 12 o'clock, 3 o'clock 6, o'clock and 9 o'clock.
The centre rotary device could for it's prime mover be electric either servo or stepper, electro mechanical or pneumatic each being motion controlled by computer. The material removing devices could remove material by sublimation or by rotary cutting with the position of the tip of the tool being controlled by linear action in two dimension, the linear action could be from sideways belt driven, rotary screw or linear motor these again being computer numerically controlled.
The information of the surface co-ordinates of the human head could be obtained via laser line reflective triangulation scanning, Moire Fringe technology or static 3D white light surface scanning giving reflected light values that can calculate a depth component. These scanners producing a co-ordinate structure in 3D of the human head and could be in the format of Cartesian, Polar or a combination of the two systems which can be used in the control of the machine via computer numeric control.
The computcr numeric control part program is of multi axis arrangement where the removal device are attached to a vertical or horizontal axis which in turn is attached to a further axis that carries the former axis, with the rotary axis being fixed in the centre of the machine.
The process starts with the surface co-ordinates of the human head these are arranged in profile lines from around the extremities of the head and are made up of an X value a Y value and a position in respect to it number within the file, with the first profile line being at zero degrees and the last being at 358.59 degrees with each profile having an even incremental value in between.
The rotational element to the part program could take the form of a fixed position for the rotary table through out each linear profile cycle or a rotational movement in between the linear profile cycles. This providing for the linear profile action to be capable in having more than one removal source for the full 360 degree cycle.
This invention will now be explained by way of example. The dimensional co-ordinates of the human head are arranged as profile lines around the head with 256 profiles each having 512 points per profile. The profile lines are of two dimensions and each having an added incremental value from 0.0 degrees to 360.0 degrees at increments of 1.40625 degrees depicting the profile lines of the circumference of the human head.
The part program is now shown for two material removal devices arranged at 180 degrees apart.
The co-ordinate file of the head is split into two sections, the first section from profile number 0 to profile number 127. The second section of the file is from 128 to 256 profile, with the first four axis values being taken from profile number 0 and number 128 for the first line of the part program and from the second four axis value of profile number 0 and number 128 for the second line of the part program and so on until the end of file.
Each axis is given a name and a co-ordinate value with axis 1 and 2 working together also axis 3 and 4 working together and when the program is run the axis controller sends each material removal device to its corresponding position. The values of Axis 1 and Axis 2 are taken from the first section of the file and the values for Axis 3 and Axis 4 are taken from the second part of the file, the Axis 5 is the rotary axis which is controlling the rotary table at the end of each profile material removing cycle. Axis 5 rotates the 1.40625 degrees and then the next two profiles are machined.

The above algorithm which generates the part program together with the material removal devices machines a reproduction of the human head in 50% of the time it would take a single material removal devices by machining V2 the head each at the same time. If a multiple of four material removal devices were used it would take 1⁄4 of the time to machine a head.
