INTRODUCTION:
Special Machines in the ridge Racer series are special vehicles that are unlocked by completing special touraments and races. The Angelus and Crinale are an example of a one of a kind special machine.
Mathematical analysis
The Enigma transformation for each letter can be specified mathematically as a product of permutations. Assuming a three-rotor German Army/Air Force Enigma, let denote the plugboard transformation, denote that of the reflector, and denote those of the left, middle and right rotors respectively. Then the encryption can be expressed as
Special purpose lathes:
Special purpose lathes machines are designed for producing definite type of work that involves certain specific operations that cannot be performed on standard lathe machines.
SPECIAL TYPES OF DRILLING MACHINES:
There are a number of types of special purpose drilling machines. The purposes of these types of drilling machines vary. Special purpose drilling machines include machines capable of drilling 20 holes at once or drilling holes as small as 0.01 of an inch.
GANG DRILLING MACHNES:
The gang style drilling machine (Figure 4) or gang drill press has several work heads positioned over a single table. This type of drill press is used when successive operations are to be done. For instance, the first head may be used to spot drill. The second head may be used to tap drill. The third head may be used, along with a tapping head, to tap the hole. The fourth head may be used to chamfer.
